Method of correlation functions,t is of great fundamental importance, serving as a starting point for derivation of distribution functions of small (but macroscopic) subsystems corresponding to the canonical and grand canonical ensemble. But the latter are still difficult (in fact virtually impossible) to calculate for realistic i

Equations of state, to observable macroscopic properties. There are three such routes, provided by.equations of state. This brings us to a problem of thermodynamic consistency. As we will see later, all these equations require a knowledge of correlation functions. Since exact correlation functions for realistic potent

Liquid-vapor interface, liquid and its saturated vapor at temperature .. The two-phase equilibrium is characterized by equality of temperature, pressure, and chemical potentials in both bulk phases (see Chap. 6). The density, however, is not constant but varies continuously along the interface between two bulk equilibrium

Equilibrium phase transitions,c common feature is an abrupt change in certain properties. For example, when ice is heated, its state first changes continuously up to the moment when the temperature reaches 0°C (at normal pressure), at which point ice begins transforming into liquid water with absolutely different properties.

Real gases,al gases on a satisfactory level?” might seem rather trivial. However, it is not. The simplest thermodynamic description of a real gas can be obtained from the virial expansion, which for low densities one can truncate at the second-order term: . which contains the second virial coefficient ..
