The molar heat capacity is zero

Vedclass · Answer

(C) In an adiabatic process,there is no exchange of heat between the system and the surroundings,so $dQ = 0$.By definition,the molar heat capacity $C$ is given by $C = \frac{dQ}{n dT}$.Since $dQ = 0$,the molar heat capacity $C = 0$.According to the first law of thermodynamics,$dQ = dU + dW$. Since $dQ = 0$,we have $dU = -dW$,which means the work done by the gas is equal to the decrease in internal energy.Therefore,the statement that the molar heat capacity is zero is correct.
