Enthalpy | Specific heat

Enthalpy:-
Enthalpy is a property which is defined as the sum of inter-molecular energy and the product of pressure and volume of a system. It is denoted by symbol ' H '.
                            H=U+pV
Enthalpy H is an extensive property. The corresponding intensive property, the specific enthalpy h, is defined as
                           h=u+pv

Specific heat:-
The specific heat of a substance is defined as the amount of heat required to raise a unit mass of the substance through a unit rise in temperature. The symbol ' C ' will be used for specific heat.
Therefore,   C= Q/m.∆t J/kg k

Specific heat at constant volume:-
specific heat at constant volume is defined as the change of specific inter-molecular energy with temperature at constant volume.

                                              

Specific heat at constant pressure:-

specific heat at constant pressure is defined as the change of specific

enthalpy at constant pressure.
