Specific heat capacities at constant volume (Cv) were measured with an adiabatic calorimeter for pure pentafluoroethane (R125) and an azeotrope-like mixture of R32 and R125 (R410A) with a mole fraction composition of 0.6975 difluoromethane + 0.3025 pentafluoroethane. Temperatures ranged from 300...
A critical analysis of the published excess molar volumes for binary decalin+tridecane and decalin+tetradecane mixtures revealed that the values determined at low decalin mole fraction compositions were not consistent with values measured at higher decalin compositions. The analysis further showed that the...
