A CLASS OF TWO-PHASE STATE EQUATIONS

Abstract

The properties of a particular class of elementary, two-phase state equations are found to be simply related. The class includes some familiar equations, such as the Van der Waals, Berthelot, and Clausius types, as well as a form recently suggested by J. J. Martin. Conditions for stable equilibrium are given, and some examples are compared. A table of values is included which can be used with elementary transformations to find the equilibrium coexistence properties of any member of the set. A drawback for this type equation along the critical isotherm is noted.
