In this experiment, the ratio of specific heat capacities for air is determined using Ruchardt’s method of measuring the period of oscillation of the piston in a cylinder filled with air.
A cylinder is filled with air and a Pressure Sensor is attached. The piston is plucked by hand and allowed to oscillate. The oscillating pressure is recorded as a function of time and the period is determined. The ratio of specific heat capacities is calculated using the period of oscillation, according to Ruchardt’s method.
PASCO Advantage: Since the oscillations are plotted, it is easy to accurately measure the period of oscillation.
