CALCULATION OF THE CALORIC PROPERTIES OF POLAR FLUIDS

Isochoric, isobaric and saturation heat capacities of polarizable dipo lar hard-sphere fluids with variable polarizability were calculated al ong with - and in the vicinity of - the vapour-liquid coexistence curv e. As prerequisites of the calculation, orthobaric densities, vapour p ressures and heats of vaporization were also calculated. The calculate d heat capacities show realistic behaviour in the vicinity of the phas e-transition and seem to be suitable for the description of real fluid s. Therefore, the caloric properties of water, ammonia and carbon mono xide were also calculated by perturbation theory. A comparison was mad e between the calculated and experimental results.
