Vedclass · Answer

(C) The specific heat capacity of a gas is defined as $C = \frac{dQ}{m \cdot dT}$.Since the heat capacity depends on the process (the path taken),for a given temperature change $dT$,the heat supplied $dQ$ can vary depending on the process.For an isothermal process,$dT = 0$,so $C = \frac{dQ}{0} = \infty$.For an adiabatic process,$dQ = 0$,so $C = \frac{0}{m \cdot dT} = 0$.Therefore,the specific heat of a gas can take any value between $0$ and $\infty$ depending on the thermodynamic process.
