Specific Heat:
The specific Heat of a solid or liquid can be usually defined as heat required for raising unit mass through one degree temperature rise. That is,
dQ = mcdT;
dQ = mCpdT; For reversible non flow process at the constant pressure;
dQ = mCvdT; For reversible non flow process at the constant volume;
Cp = Heat capacity at the constant pressure
Cv = Heat capacity at the constant volume
