Heat capacity:

1. Heat capacity is the amount of heat energy required to raise the temperature of the entire body by $1^{\circ}C$.

2. Heat capacity depends both on the nature of the substance and the mass of the body. As the mass of the body increases the heat capacity of the body also increases.

3. Heat capacity

$C=\frac{Q}{\Delta t}\\ C = mass (m) \times specific \: heat \: capacity (c)$

4. The unit of Heat capacity is $J-K^{-1}$.

Specific heat capacity:

1. Specific heat capacity is the amount of heat energy required to raise the temperature of the unit mass of the body by $1^{\circ}C$.

2. Specific heat capacity does not depend on the mass of the body, but it is the characteristic property of the substance of the body.

3. Specific heat capacity

$C=\frac{Q}{m\Delta t} \\
C=\frac{Heat \: Capacity \: (C)}{Mass (m)}$

4. Its unit is $J-kg^{-l}-K^{-1}$.
