The rate of change of specific enthalpy with temperature at constant pressure is called:
Specific heat at constant pressure
Specific heat at constant pressure is \(c_p=\left(\frac{\partial h}{\partial T}\right)_p\), where h is enthalpy per unit mass. The derivative of total enthalpy H instead gives the total heat capacity.
