Abstract
The value and uses of supersonic velocity and absorption measurements are reviewed, and evidence that sound velocity measurements may still be used for heat capacity determinations is presented. An apparatus which is designed for (1) a general study of acoustical dispersion, and (2) the supersonic measurement of gaseous heat capacities. The general experimental technique to be used with such an apparatus is outlined, and results of measurements of the velocity of sound in air and of the heat capacity of propylene are briefly discussed.Keywords
