The pressure for systems with small z, whose interaction is stable and rapidly decreasing, is written as a functional of the correlation functions. The differential equation of state is obtained for such systems. The integration of this equation leads to the generalized virial expansion....

2. Real Gases: - Real gases deviate from ideal behavior due to the presence of intermolecular forces (attractive and repulsive) and the finite volume occupied by gas molecules. These deviations become significant at high pressures and low temperatures. 3. Reasons for Deviation: - Intermolecular For...

There are no attractive or repulsive forces between the molecules or the walls of the container. Van der Waals (1873) attempted to eliminate these two assumptions in developing an empirical equation of state for real gases. In his attempt to eliminate the first assumption, van der Waals pointed...
The general thermodynamic structure of equations of state is discussed. It is pointed out that empirical equations of state always involve a double set of assumptions. A recipe for producing thermodynamically consistent empirical equations of state is presented and is illustrated in the step-by-step ...
A simple quantitative equation of state of the van der Waals type is proposed for dense fluids. The equation yields compressibility factors with a precision comparable to those from the more complicated temperature perturbation theory when tested against ``computer experiments'', including isotherms as...

The gas laws of Boyle and Charles and Gay-Lussac can be combined into a single equation of state: PV = nRT, where p is pressure, V is volume, T is absolute temperature, n is number of moles, and R is the universal gas constant (Atkins PW, Atkins P, De Paula J (2001) Physical ...
