Up to the present time there does not appear to have been any calorimetric measurements of the heat capacity of gaseous tetrafluoromethane. Consequently this compound has been included in a continuing program of study of the constant-volume heat capacity Cv of gases at the University of Michigan. The equipment for making these measurements consists primarily of an 8-in. diameter thin-wall stainless-steel sphere mounted in an evacuated chamber with a heat shield surrounding the sphere. The sphere is equipped with a platinum heating coil, which doubles as a resistance thermometer, and a small motor-driven fan that circulates the charge of gas inside the sphere. Complete details are described elsewhere (4, 7, 9 ) , and only the calibration procedure with tetrafluoromethane is covered here.
