प्रश्न
Express the change in internal energy in terms of molar specific heat capacity.

उत्तर
When the gas is heated at constant volume the temperature increases by dT. As no work is done by the gas, the heat that flows into the system will increase only the internal energy. Let the change in internal energy be dU. dU = µωdT
