27: Specific Heat Capacities of Gases
- #3Can we define specific heat capacity for an adiabatic process?Ans : Specific heat capacity, `` s=\frac{\,\mathrm{\,\Delta \,}Q}{m\,\mathrm{\,\Delta \,}T}``, where`` ∆``Q/m is the heat supplied per unit mass of the substance and `` ∆``T is the change in temperature produced. In an adiabatic process, no heat exchange is allowed; so, `` ∆``Q = 0 and hence, s = 0. Therefore, in an adiabatic process, specific heat capacity is zero.
