Equations of state are generally expressions that relate the macroscopic observables, or state variables, such as pressure, p, volume, V, and temperature, T.

General

Virial equations of state

Semi-empirical equations of state

Naturally there is the ideal gas equation of state. However, one of the first steps towards a description of realistic substances was the famous van der Waals equation of state. Since then a plethora of semi-empirical equations have been developed, often in a similar vein to the van der Waals equation of state, each trying to better reproduce the foibles of the many gasses and/or liquids that are often of industrial interest.
