The molar heat capacity at constant pressure Cp,m and the differential Joule-Thomson coefficient m of 1,1,1,2-tetrafluoroethane, 1,1-difluoroethane, and of a mixture of equal amounts of both substances have been measured by flow calorimetry. The investigation covered gaseous and supercritical states
The speed of sound u is both formally independent of the amount of substance and can be measured easily with high precision (typically u/u < 1β’10 -5 ). Measurement of this quantity offers a favorable route for obtaining density Ο, molar isochoric heat capacity C V,m , and molar isobaric heat capacit
