Question

What is the relation between $C_p$ and $C_v$ ?

Answer 1

$C_p$ - specific heat capacity of substance at constant pressure

$C_v$ - specific heat capacity of substance at constant volume.

Relations :

$C_p-C_v=R$ where, R - gas constant.

$\frac{C_p}{C_v}=\gamma$ (specific heat capacity ratio called 'gamma').
