Write definitions of molar specific heat at constant pressure and constant volume.
(N/A) $1$. Molar specific heat at constant volume $(C_V)$: It is defined as the amount of heat required to raise the temperature of $1 \text{ mole}$ of a gas by $1 \text{ K}$ (or $1^{\circ}\text{C}$) while keeping its volume constant.
$2$. Molar specific heat at constant pressure $(C_P)$: It is defined as the amount of heat required to raise the temperature of $1 \text{ mole}$ of a gas by $1 \text{ K}$ (or $1^{\circ}\text{C}$) while keeping its pressure constant.
