Vedclass · Answer

(C) For a monoatomic gas,the molar heat capacity at constant pressure is $C_p = \frac{5}{2} R$ and at constant volume is $C_v = \frac{3}{2} R$.The heat supplied at constant pressure is given by $dQ = n C_p dT = n \left( \frac{5}{2} R \right) dT$.The work done by the gas at constant pressure is $dW = P dV = n R dT$.Dividing the work done by the heat supplied,we get:$\frac{dW}{dQ} = \frac{n R dT}{n (\frac{5}{2} R) dT} = \frac{1}{5/2} = \frac{2}{5}$.Therefore,the work done by the gas is $dW = \frac{2}{5} Q$.
