Editing Equations of state

'''Equations of state''' are generally expressions that relate the macroscopic observables, or ''state variables'', such as  [[pressure]], <math>p</math>, volume, <math>V</math>, and [[temperature]], <math>T</math>. 
==General==
*[[Common bulk modulus point]]
*[[Law of corresponding states]]
*[[Linear isothermal regularity]]
*[[Maxwell's equal area construction]]
*[[Tait-Murnaghan relation]]
*[[Zeno line]]

==Virial equations of state==
*[[Virial equation of state]]
*[[Second virial coefficient]]
*[[Virial coefficients of model systems]]
==Semi-empirical equations of state==
Naturally there is the [[Equation of State: Ideal Gas|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.
