![]() ![]() The period of oscillation of a mass on a spring (or for the piston and air) is The piston acts as the mass and the air acts as the spring. Just like a mass on a spring, the piston will oscillate. If the piston is displaced downwards a distance x, there will be a restoring force which forces the piston back toward the equilibrium position. ![]() Gamma, the ratio of specific heat, can be determined by measuring the period of oscillation. The piston will then oscillate about the equilibrium position. In Ruchhardt's Method, a cylinder of gas is compressed adiabatically by plucking the piston. The ratio of specific heat capacities is calculated using the period of oscillation, according to Ruchhardt's method. The oscillating pressure is recorded as a function of time and the period is determined. The piston is plucked by hand and allowed to oscillate. Ratio of Specific Heats of a Gas EX-5531 Page ofĪ cylinder is filled with air and a Pressure Sensor is attached. ![]()
