Cp and Cv for Liquids & Solids

Definition of molar enthalpy :
For small to moderate changes in T and P, the Molar volume of most liquids and solids remains nearly constant.
Therefore :
The molar volume of solids and liquids is generally quite small.
Therefore, for small to moderate changes in P :
The Constant Volume Heat Capacity is defined by:
The Constant Pressure Heat Capacity is definied by:
Therefore, we obtain the following useful relationships:
