Assertion : The specific heat of a gas in an adiabatic process is zero and in an isothermal process is infinite.
Reason : Specific heat of gas is directly proportional to change of heat in system and inversely proportional to change in temperature.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Solution
In adiabatic process, no heat transfer takes place between gas and surrounding i.e., $\Delta Q=0$ From definition of specific heat, $C=\frac{\Delta Q}{m \Delta T}=0$ Again, for isothermal process, $\Delta T=0$
$\therefore \quad C=\frac{\Delta Q}{m \Delta T}=\infty$
