T is intensive, however, and it makes no sense to consider a repartitioning of an intensive variable. Thus if the pressure of a stable , system is increased isothermally its volume will decrease.

A general rule for stability criteria should now be apparent. Let stand for the internal energy or a Legendre transform of it which is a natural function of the extensive variables Xl,. However, the second law i. Triple point": a-p-7 phase equilibria " T Fig.

A hypothetical phase diagram. Here, jicja is the mole fraction of species i in phase or. This formula is the Gibbs phase rule. As an illustration, consider a one-component system.

Without coexisting phases, there are two degrees of freedom; p and T are a convenient set. The system can exist anywhere in the p-T plane. Three phases coexist at a point, and it is impossible for more than three phases to coexist in a one-component system. Thus, a possible phase diagram is illustrated in Fig.

For example, the content of the first of these equations is illustrated in Fig. The second law says that at constant T p, and n, the stable , equilibrium state is the one with the lowest Gibbs free energy which is «jU for a one-component system. This condition determines which of the two surfaces corresponds to the stable phase on a particular side of the oc-fi coexistence line.

According to this picture, a phase transition is associated with the intersection of Gibbs surfaces. Chemical potential surfaces for two phases. If the two surfaces happen to join smoothly to one another, then v and 5 are continuous during the phase change. When that happens, the transition is called second order or higher order.

A first-order transition is one in which, for example, v T, p is discontinuous. For a one-component system, a second-order transition can occur at only one point-a critical point. In a two-component system, one can find lines of second-order phase transitions, which are called critical lines. An isotherm in the p-v plane. Notice that the right-hand side is ill-defined at a second- order phase transition.

Another way to view phase equilibria is to look at a thermo- dynamic plane in which one axis is an intensive field and the other axis is the conjugate variable to this field.

For example, consider the p-v plane for a one-component system In Fig. Notice how v T,p is discontinuous i. Here is a puzzle to think about: For water near 1 atm pressure and 0oC temperature, the solid phase, ice I, has a larger volume per mole than the liquid. Which one might be an isotherm for water? Wouldn t this behavior violate stability? Perhaps Fig. Isobar in the v-Tplane. For many systems the , picture looks like that shown in Fig. At times this representation is very informative.

But sometimes it becomes difficult to use because v and T are not conjugate, and as a result, v T,p is not necessarily a monotonic function of T. The a vs. A questionable Helmholz free energy per mole on an isotherm. Finally, since p is fixed by T when two phases are in equilibrium, the double tangent line drawn between u a and is the free energy per mole in the two-phase region v a! Phase diagram for a simple material. One assumes for these theories that the instability is bridged by a phase transition located by a Maxwell construction the dashed line.

Show that below a certain temperature the van der Waals equation of state implies a free energy that is unstable for some densities. For example, in a one- component simple fluid like argon the phase diagram looks like the diagram pictured in Fig. If an approximate theory is used in which an instability is associated with a phase transition, the locus of points surrounding the unstable region is called the spinodal.

The spinodal must be enveloped by the coexistence curve. For example the van der Waals , equation yields a diagram like the one pictured in Fig. If two phases are in equilibrium, there is a surface or interface of material between them. Let us now focus attention on this interface. See Fig. The density profile near the interface is sketched in Fig. In this figure, p z is the number of moles or molecules per unit volume of a particular species, zd is the arbitrary location of the dividing surface, and w is the width of the interface typically a few molecular diameters.

Construction - i v l [y gas j-l UquiiDj - Fig. Coexistence curves and spinodals. This surface energy should depend upon the surface area, a. The property y is called the surface tension. It is intensive by virtue of its definition. It also should be positive.

If not, lower energy states would be obtained by making the phase boundary more irregular since the irregularity will increase the surface area. Therefore, a negative surface tension would drive the system to a terminal state in which the surface was spread over the whole system.

The boundary between two phases would then cease to exist, and there would be no " " surface. Since the interface exists when there is two-phase equilibria, the Gibbs phase rule tells us that y is determined by r intensive variables where r is the number of components. For one component, T suffices. Clearly, E is first order homogeneous in 5, V, n, and a.

Hypothetical interface between two phases a and p. Density profile. This means that there will be surface interaction energies with the walls that are also proportional to o. How do we separate these energies from ycr? Can you think of procedures to do this? Consider two sorts: i Make measurements of containers filled with pure vapor, pure liquid, and a mixture of the two.

The latter might be dificult in practice, but could be feasible in the world one can simulate with computers see Chapter 6. Imagine a hypothetical phase that would result if phase a maintained its bulk properties right up to the mathematical dividing surface. In other words, the surface tension is the surface Helmholtz free energy per unit area. By virtue of its definition, y also plays the role of the force constant in the restoring force that inhibits the growth of surface area [i.

In the choice of Gibbs surface previously discussed, we removed the term in E that depends upon mole number. The energetics of the surface is a result of the repartitioning of the bulk phases that occurs if the surface is altered. The absence of any dependence on mole number, however, can only be accomplished for one species.

To develop the surface energy expressions for a mixture, we begin with our expression for dEis before the Gibbs surface is employed. At constant T this yields ody - -n dfa- The solution to this equation is called the Gibbs adsorption isotherm.

Sprinkle pepper on its surface. Touch a bar of soap to the surface in the middle of the bowl. What happened? Touch the surface with the soap again, and again.

What happened and why? First, let us consider two immiscible liquids, perhaps an oil and water equilibrium. In a gravitational field, the heavier phase will fall to the bottom of the container, and a planar interface will form between the two liquids. In the absence of gravity, we can imagine that one of the fluids forms a spherical drop of liquid surrounded by the other species of fluid.

We suspect that the drop would be spherical since this shape will minimize the surface area of the interface and thereby minimize the contribution to the free energy from the surface tension. The restoring force that opposes this deforma- tion is proportional to the surface tension.

When this tension vanishes, the deformations are not hindered; the interface will then fluctuate wildly, the drop will become amoeboid and eventually disintegrate. In other words, the two fluids will mix. In some cases, the mixing of the phases is associated with the formation of small assemblies such as micelles.

A typical micelle is an aggregate involving roughly surfactant molecules. Here one , imagines that the charged or polar head groups lie on a surface surrounding the hydrophobic tails and oil thus inhibiting contact between the water and oil. The surface tension, however, is relatively low so that the shapes of these assemblies undoubtedly fluctuate appreciably. Further, if one considers small enough systems at a truly molecular level, fluctuations are almost always significant.

Statistical mechanics is the subject that describes the nature of these fluctua- tions, our next topic in this book. In Chapter 6 we study the phase equilibrium of a small system by a numerical Monte Carlo simulation. A glance at the results of those simulations provides ample evidence of the importance of fluctua- tions at interfaces. Their importance must be considered carefully in any microscopic formulation of interfacial phenomena.

Indeed, the reader may now wonder whether an interface with an intrinsic width as pictured at the beginning of this section is actually well defined at a ' microscopic level. It s an important and puzzling issue worth thinking about. Additional Exercises 2 Show that. That is, they possess a hydrophilic charged or polar head group, and a hydrophobic oil-like tail.

Given this fact, determine whether a rubber band will contract or expand when it is cooled at constant tension. Which has the largest increase in temperature?

Which of these is correct? Given this fact, determine what happens to the temperature of a paramag- netic material when it is adiabatically demagnetized. Consider a one-component system when two phases, or and are in equilibrium.

A hypothetical experimentalist measures the hypothetical equation of state for a substance near the liquid-solid phase transition.

At a given temperature, the pressure of the liquid can be adjusted to a particular pressure, ps, at which point the liquid freezes.

Sebba in. CHAPTER 3 Statistical Mechanics We now turn our attention to the molecular foundation of thermo- dynamics, or more generally, the answer to the following question: If particles atoms, molecules, or electrons and nuclei, That is, we want to discuss the relationship between the microscopic dynamics or fluctuations as ' ' governed by Schrodinger s equation or Newton s laws of motion and the observed properties of a large system such as the heat capacity or equation of state.

At first you might think that as the number of particles increases, the complexity and obscurity of the properties of a mechanical system should increase tremendously, and that you would be unable to find any regularity in the behavior of a macroscopic body.

But as you know from thermodynamics, large systems are, in a sense, quite orderly. An example is the fact that at thermodynamic equilibrium one can characterize observations of a macroscopic system with only a handful of variables.

The attitude we shall take is that these distinctive regularities are consequences of statistical laws governing the behavior of systems composed of very many particles. The word "measurement" is important in these remarks. If we imagined, for example, observing the time evolution of one particular particle in a many-body system, its energy, its momentum, and its position would all fluctuate widely, and the precise behavior of any of these properties would change drastically with the application of the slightest perturbation.

One cannot imagine a reproducible measure- ment of such chaotic properties since even the act of observation involves a perturbation. These variables are initial coordinates and momenta of all the particles if they are classical, or an equally cumbersome list of numbers if they are quantal. If we would fail to list just one of these variables, the time evolution of the system would no longer be deterministic, and an observation that depended upon the precise time evolution would no longer be reproducible.

It is beyond our capacity to control variables. As a result, we confine our attention to simpler properties, those controlled by only a few variables.

In some areas of physical and biological science, it might not be easy to identify those variables. But as a philosophical point, scientists approach most observations with an eye to discovering which small number of variables guarantees the reproducibility of phenomena. The use of statistics for reproducible phenomena does not imply that our description will be entirely undeterministic or vague. To the contrary, we will be able to predict that the observed values of many physical quantities remain practically constant and equal to their average values, and only very rarely show any detectable deviations.

For example, if one isolates a small volume of gas containing, say, only 0. As a rough rule of thumb: If an observable of a many particle system can be specified by a small number of other macroscopic properties, we assume that the observable can be described with statistical mechanics.

For this reason, statistical mechanics is often illustrated by applying it to equilibrium thermo- dynamic quantities. While it is not possible in practice, let us imagine that we could observe a many-body system in a particular microscopic state.

To specify the state V at a particular time, we need a number of variables of the order of N, the number of particles in the system. Consider, for example, stationary solutions?

The index v is then the collection of D. N quantum numbers, where D is the dimensionality. Once the initial state is specified, if it could be, the state at all future times is determined by the time integration of Schrodinger's equation. Points in phase space characterize completely the mechanical i. Exercise 3. Now try to think about this time evolution-the trajectory-of a many-body system.

As illustrated in Fig. In preparing the system for this trajectory a certain small number of variables is controlled. For example, we might fix the total energy, E, the total number of particles, N, and the volume, V. These constraints cause the trajectory to move on a "surface" of state space-though the dimensionality of the surface is still enormously high.

Trajectory in state space with each box representing a different state. A basic concept in statistical mechanics is that if we wait long enough, the system will eventually flow through or arbitrarily close to all the microscopic states consistent with the constraints we have imposed to control the system. Suppose this is the case, and imagine that the system is constantly flowing through the state space as we perform a multitude Jf of independent measurements on the system, The observed value ascertained from these measurements for some property G is 1 aobs where Ga is the value during the ath measurement whose time duration is very short-so short, in fact, that during the ath measurement the system can be considered to be in only one microscopic state.

The term in square brackets is the probability or weight for finding the system during the course of the measurements in state v. Remember, we believe that after a long enough time, all states are visited.

V The averaging operation i. An ensemble is the assembly of all possible microstates- " all states consistent with the constraints with which we characterize the system macroscopically. The canonical ensemble, another example, considers all states with fixed size, but the energy can fluctuate. The former is appropri- ate to a closed isolated system; the latter is appropriate for a closed system in contact with a heat bath.

There will be much more said about these ensembles later. The idea that we observe the ensemble average, G , arises from the view in which measurements are performed over a long time, and that due to the flow of the system through state space, the time average is the same as the ensemble average.

The equivalence of a time average and an ensemble average, while sounding reasonable, is not at all trivial.

Dynamical systems that obey this equivalence are said to be ergodic. It is dificult, in general, to establish the principle of ergodicity, though we believe it holds for all many-body systems encountered in nature.

It is often true for very small systems too, such as polyatomic molecules. Indeed, the basis of the standard theories of unimolecular kinetics rests on the assumed ergodic nature of intramolecular dynamics.

That is, describe systems that do not sample all possible states even after a very long time. Incidentally, suppose you thought of employing stationary solu- tions of Schrodinger's equation to specify microscopic states. If truly in a stationary state at some point in time the system will remain , there for all time, and the behavior cannot be ergodic. But in a many-body system, where the spacing between energy levels is so small as to form a continuum, there are always sources of perturba- tion or randomness the walls of the container, for example that make moot the chance of the system ever settling into a stationary state.

The primary assumption of statistical mechanics-that the ob- served value of a property corresponds to the ensemble average of that property-seems reasonable, therefore, if the observation is carried out over a very long time or if the observation is actually the average over very many independent observations. The two situa- tions are actually the same if "long time" refers to a duration much longer than any relaxation time for the system.

The idea that the system is chaotic at a molecular level leads to the concept that after some period of time-a relaxation time, rrelax-the system will lose all memory of i.

In practice, we often consider measurements on macroscopic systems that are performed for rather short periods of time, and the concept of ensemble averages is applicable for these situations, too. This can be understood by imagining a division of the observed macroscopic system into an assembly of many macroscopic sub- systems. If the subsystems are large enough, we expect that the precise molecular behavior in one subsystem is uncorrected with that in any of the neighboring subsystems.

The distance across one of these subsystems is then said to be much larger than the correlation length or range of correlations. When subsystems are this large they behave as if they are macroscopic. Under these conditions one , instantaneous measurement of the total macroscopic system is equivalent to many independent measurements of the macroscopic subsystems. The many independent measurements should correspond to an ensemble average. Thermodynamics The basic idea of statistical mechanics is, therefore, that during a measurement, every microscopic state or fluctuation that is possible does in fact occur, and observed properties are actually the averages from all the microscopic states.

To quantify this idea, we need to know something about the probability or distribution of the various microscopic states. In other words, the macroscopic equilibrium state corresponds to the most random situation-the distribution of microscopic states with the same energy and system size is entirely uniform.

For notational and perhaps conceptual simplicity we often omit , subscripts and simply write N to refer to the number of particles and , we use the volume V to specify the spatial extent of the system. Our remarks, however, are not confined to one-component three- dimensional systems. The width 5E is some energy interval charac- teristic of the limitation in our ability to specify absolutely precisely the energy of a macroscopic system.

If 5E was zero the quantity , Q iV, Vy E would be a wildly varying discontinuous function, and when it was non-zero, its value would be the degeneracy of the energy level E.

It will turn out that the thermodynamic consequences are extraordinarily insensitive to the size of 5E. The reason for the insensitivity, we will see, is that Q iV, V, E is typically such a rapidly increasing function of Ey that any choice of SE E will usually give the same answer for the thermodynamic consequences examined below.

Due to this insensitivity, we adopt the shorthand where the symbol SE is not included in our formulas. For macroscopic systems, energy levels will often be spaced so closely as to approach a continuum. In the applications we pursue, however, we will have little need to employ this notation.

The definition is also consistent with the variational statements of the second law of thermodynamics. Any specific partitioning is a subset of all the allowed states, and therefore the number of states with this partitioning, Q N, V, E; internal constraint is less than the total number Q N, V, E.

This inequality is the second law, and we now see its statistical meaning: the maximization of entropy coinciding with the attainment of equilibrium corresponds to the maximization of disorder or molecular randomness. The greater the microscopic disorder the , larger the entropy. The thermodynamic condition that temperature is positive requires that Q N, V, E be a monotonic increasing function of E.

For macroscopic systems encountered in nature, this will always be the case. Everything looks fine until we realize that the degeneracy of the most excited state is 1.

Thus, at some point, Q E, N, V becomes a decreasing function of E, which implies a negative temperature. How could this be? The many results derived during our discussion of that topic concerning stability, phase equilibria, Maxwell relations, etc. When applying the microcanonical ensemble the natural variables , characterizing the macroscopic state of the system are E V, and N. In statistical mechanics, these manipulations are related to changes in ensembles. As an important example we consider now the canonical , ensemble-the assembly of all microstates with fixed N and V.

The energy can fluctuate, however, and the system is kept at equilibrium by being in contact with a heat bath at temperature T or inverse temperature fl. Schematically, we might picture the ensemble as in Fig. This observation allows us to derive the distribution law for states in the canonical ensemble. To begin, consider the case where the bath is so large that the energy of the bath, EB, is overwhelmingly larger than the energy of the system, Ev. Assembly of states for a closed system in a heat bath.

We choose to expand In Q E rather than Q E itself because the latter is a much more rapidly varying function of E than the former. A canonical ensemble system as a subsystem to microcanonical subsystem.

In fact, we will soon show that In Q is the Helmholtz free energy. For the next few pages, however, let us take this fact as simply given.

The energies Ev refer to the eigenvalues of Schrodinger's equation for the system of interest. In general, these energies are difficult if , not impossible, to obtain. It is significant, therefore, that a canonical ensemble calculation can be carried out independent of the exact ' solutions to Schrodinger s equation.

This fact is understood as follows: V V where " Tr" denotes the trace of a matrix in this case, the trace of the Boltzmann operator matrix. It is a remarkable property of traces that they are independent of the representation of a matrix. When calculating properties like the internal energy from the canonical ensemble, we expect that values so obtained should be the same as those found from the microcanonical ensemble. Indeed, as the derivation given above indicates, the two ensembles will be equivalent when the system is large.

This point can be illustrated in ;wo ways. In other words, for large systems, the canonical partition function is the Laplace transform of the microcanonical Q E. An important theorem of mathematics is that Laplace transforms are unique.

Due to this uniqueness, the two functions contain the identical information. Nevertheless, energy luctuates in the canonical ensemble while f energy is fixed in the microcanonical ensemble. This inherent difference between the two does not contradict the equivalency of ensembles, however, because the relative size of the fluctuations becomes vanishingly small in the limit of large systems.

The result fore- shadows the topics of linear response theory and the fluctuation- dissipation theorem, which we will discuss in Chapter 8. In the present context, we use the fluctuation formula to estimate the relative r. Since the heat capacity is extensive, it is of order N where N is the number of particles in the system.

Furthermore E is also of order N. Verify this suggestion by performing a steepest descent calculation with P E. Use this expansion to estimate for 0. To calculate the thermodynamic properties of this model, we first apply the microcanonical ensemble. The degeneracy of the mth energy level is the number of ways one may choose m objects from a total of N. The continuum limit of factorials is Stirling's approximation : In M!

Of course, we could also study this model system with the canonical ensemble. System immersed in a bath. Let us consider now, in a rather general way, why changes in ensembles correspond thermodynamically to performing Legendre transforms of the entropy.

To begin, consider a system with X denoting the mechanical extensive variables. Imagine an equilibrated system in which E and X can fluctuate. It can be viewed as a part of an isolated composite system in which the other part is a huge reservoir for E and X.

An example could be an open system in contact with a bath with particles and energy flowing between the two. This example is pictured in Fig. The probability for microstates in the system can be derived in the same way we established the canonical distribution law. It is called the Gibbs entropy formula. The most important example of these formulas is that of the grand canonical ensemble. This ensemble is the assembly of all states appropriate to an open system of volume V.

It depends upon volume because the energies Ey depend upon the size of the system. Hence, the "free energy" for an open system, fipV, is a natural function of P, fa, and V. Fluctuation formulas in the grand canonical ensemble are analyzed in the same fashion as in the canonical ensemble.

Generalizations to multicomponent systems can also be worked out in the same way, and they are left for the Exercises. Recall that in our study of thermodynamic stability i. Now we see the same result in a different context.

The right-hand side is manifestly positive, and the left-hand side determines the curvature or convexity of a thermodynamic free energy. Partitioning into cells. In the illustration, we consider concentration or density f uctuations in a system of uncorrelated particles, and we show that l the ideal gas law i.

We will return to the ideal gas in Chapter 4 where we will derive its thermodynamic properties from detailed considerations of its energy levels. The following analysis, however, is of interest due to its generality being applicable even to large polymers at low concentration in a solvent, To begin we imagine partitioning the volume of a system with cells as pictured in Fig.

Fluctuations in the region of interest follow the grand canonical distribution law described in Sec. We will assume that the cells are constructed to be so small that there is a negligible chance for more than one particle to be in the same cell at the same time. Therefore, we can characterize any statistically likely configurations by listing the numbers azx, rij,. A simplification is found by considering the case in which different particles are uncorrelated with each other and this lack of correlation is due to a very low concentration of particles.

Hence, on the average, each cell behaves identically to every other cell. By itself, this relationship is already a remarkable result, but its thermodynamic ramification is even more impressive. In particular, since the region of interest is described by the grand canonical ensemble, we know that see Sec. Further, from standard manipulations see Exercise 1. Generalizations to multicomponent systems are straightforward and left for Exercises.

Alternatively, we could begin with the second law and the Gibbs entropy formula rather than deducing them from the principle of equal weights. In the next few pages we follow this alternative development.

Two independent subsystems A and B. Consider a system contained in two boxes, A and B see Fig. Denote the total entropy of the system by SAB. The ensemble appropriate to such a system is the microcanonical ensemble: the assembly of all states with E , N, and V fixed. To derive the equilibrium probability for state Pj, we require that the condition for thermodynamic equilibrium be satisfied. In other words, the partitioning of microscopic states at equilibrium is the partitioning that maximizes the entropy.

V, and T are fixed, but the energy is not. By combining Eqs. Note that in the variation of E , we do not alter Ej since the variation refers to changes in i. From thermodynamic considerations alone, it is clear that the knowledge of Q tells us everything about the thermodynamics of our system. Similar analysis can be applied to other ensembles, too. In general, therefore, the principle of equal weights is equivalent to the Gibbs entropy formula and the variational statement of the second law of thermodynamics.

Additional Exercises 3. By applying Gibbs entropy formula and the equilibrium condition derive the probability distribution for the grand canonical ensemble-the ensemble in which N and E can vary. The former determines the size of the mean square energy fluctuations in the canonical ensemble where density does not fluctuate, and the latter determines the size of the mean square density fluctuations.

For 0. Consider a system of N distinguishable non-interacting spins in. Each spin has a magnetic moment of size jit, and each can point either parallel or antiparallel to the field. Consider the system studied in Exercises 3.

Use an ensemble in which the total magnetization is fixed, and determine the magnetic field over temperature, pH, as a function of the natural variables for that ensemble. Show that in the limit of large N, the result obtained in this way is equivalent to that obtained in Exercise 3.

Nevertheless, the two computa- tions should yield the same result. The two calculations yield the same result, though the second is algebraically more tedious. You might find it useful to organize the algebra in the second case by exploring the properties of Pauli spin matrices. Why does m increase with increasing 3 The volume of the region is L3. Due to the spontaneous fluctuations in the system, the instantaneous value of the density in that region can differ from its average by an amount dp.
