The fact that internal energy of a mixture is equal to the sum of the partial internal energies of the gases can also be applied to properties like H,Cv,Cp,S,F, and G.

Question

Quizplus · Accepted Answer

The properties H (enthalpy), Cv (specific heat at constant volume), Cp (specific heat at constant pressure), S (entropy), F (Helmholtz free energy), and G (Gibbs free energy) of a mixture can indeed be expressed as the sum of the partial properties of the individual gases in the mixture, assuming ideal behavior. This is because these properties are extensive, meaning they are additive for the components of the mixture.
