3.8 Determination of γ by Clement and Desormes’ Method
The principle of the method of determination of γ by clement and Desormes is based on adiabatic expansion of gas. The arrangement is as shown in Fig.3.8. A is a large flask of nearly 30 liters capacity closed by a rubber cork through which a manometer M, a tube provided with a stopcock C for filling with the experimental gas and an arrangement D for adiabatic expansion of the gas are provided. A is kept inside a bowl B packed with insulating material such as cotton, wool, asbestos fiber etc, suitable for adiabatic expansion of gas in A. The manometer M is provided with sulphuric acid or suitable oil as manometer liquid.
