Description:
This demonstration measures the ratio Cp/Cv, the ratio of specific heat at constant pressure to specific heat at constant volume. The demo consists of a tube in a rubber stopper which fits into a flask. A metal ball is dropped into the tube and oscillates. By measuring the period of the oscillations, the ratio can be determined by using the equation [missing image], where a is the radius of the ball and P = Po + mg/a.
