Amount of heat required to change the temperature of one unit of mass by one unit of temperature:

 c_p = \left( \frac{\delta Q}{\delta m \cdot \delta T} \right)_p

 BTU/(lbm°F)


Specific Heat Capacity depends on the PVT conditions  at which the heat transfer is happening and thus.


The two major heat transfer processes are isobaric and isohoric which define isobaric specific heat capacity  and isochoric specific heat capacity , both characterising the properties of matter.
