A resonance apparatus for the measurement of Cp/Cv for different gases is described. In the apparatus a magnetically supported piston in a vertical cylindrical glass tube containing the gas is forced into oscillation by means of a standard audio signal generator. The apparatus is simple and inexpensive, and may be used for general work on forced oscillations and resonance.
