✦ Synopsis

THE equation of state of a mixture in its most general form involving Ma gram atoms of the constituent a, Mb gram atoms of the constituent b, etc., which may combine to form various molecules, is p = ¢'(T, v, Mo, Mb, "-), (i) where p, v, and T denote respectively the pressure, volume, and absolute temperature T of the mixture. Since the pressure p does not depend on the total masses of the constituents, but on their partial densities, the quantities v, M~, Mb, ..are associated with each other in the form of the ratios M~/v, Mb/v, ..., and hence equation (I) should be written

M~ Mb

) P=~T,v, v (2) § 2.

PROPERTIES OF THE EQUATION OF STATE IN RESPECT TO THE TEMPERATURE

If the masses Ma, Mb, -.. of the constituents are all zero while v remains finite, p is zero, and hence p may not be a function of T alone. The temperature T therefore appears in the equation only in functions of T which are factors of the ratios Ma/v, Mb/v, ..., or the foregoing equation should be written P= ¢(A1Ma, A2 M~ B1Mb B2 Mb ),
