Question

Can we define specific heat capacity for an adiabatic process?

Answer 1

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.
