A thermodynamic equation relating state variables in thermodynamic equilibrium which describe the state of matter under a given set of physical conditions, such as pressure , density (or compressibility factor ), temperature or internal energy and chemical structure.

The most general form is:

f(p, T, V_m) = 0

where

	temperature
	pressure
	molar volume

Alternative forms

\rho = \rho (p,T)

Z = Z(p,T)

p = p(\rho,T)
