Can we define specific heat capacity for an adiabatic process?

The specific heat capacity of a substance is defined as the amount of heat required to raise the temperature of one mole of that substance by 1 degree Celsius, or 1 Kelvin. It is denoted by C.


Hence, , … (i) where


C = specific heat capacity


Q = heat required to raise the temperature by dT


m = molar mass


dT = change in temperature.


For an adiabatic process, Q = 0. Substituting this value in (i), we get


C = 0.


Hence, for a process at a constant temperature, the specific heat capacity is zero.
