Abstract
The ratio cp/cv at room temperature has been determined for He, A, H2, N2, O2, CO2, N2O, SO2, CH4, and C2H4 by a method of self‐sustained oscillations. The results are reproducible to within 0.1 percent and agree with the best values reported by other observers to within 0.1 percent. The method requires the measurement of a temperature, a pressure and a period of oscillation. The theory of the self‐sustained oscillations has been developed to include the effects of the mass of the oscillating gas, damping, heat conduction, and the departure of the behavior of actual gases from the ideal gas law.Keywords
