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. The ratios of specific heats, γ = (C P /C V), for three gases (air, argon and carbon dioxide) were calculated by measuring the oscillations of different masses in various apparatus.
