Isochoric, isobaric and saturation heat capacities of polarizable, dip
olar hard-sphere fluids with variable polarizability were calculated a
long with - and in the vicinity of - the vapour-liquid coexistence cur
ve. As prerequisites of the calculation, orthobaric densities, vapour
pressures and heats of vaporization were also calculated. The studied
heat capacities show realistic behaviour in the vicinity of the phase-
transition, and seem to be suitable for the description of real fluids
.
