Summary
Using the acoustical interferometer for high pressures described in an earlier publication1) we measured the velocity of sound in oxygen gas between 1 and 70 atm as a function of pressure at different temperatures. From the experimental data we calculated the change of the ratio of the specific heats and the specific heats themselves as a function of pressure at the different temperatures.
