| Abstract |
The authors present measurements of the speed of sound in gaseous difluoromethoxy-difluoromethane (CHF2-O-CHF2) and 2-difluoromethoxy- 1,1,1-trifluoroethane (CF3-CH2-O-CHF2). These measurements were performed in an all-metal apparatus between 255 and 384 K. The authors have obtained ideal-gas heat capacities and second acoustic virial coefficients from analysis of these measurements. Two methods of correlating the second acoustic virial coefficients, a squarewell model of the intermolecular interaction and a function due to Pitzer and Curl, are presented. |
