(i) Difference between "Heat Capacity" and "Specific Heat Capacity" are as follows :
| Heat Capacity | Specific Heat Capacity |
|---|---|
| It is the amount of heat energy required to raise the temperature of entire body by 1 °C. | It is the amount of heat energy required to raise the temperature of unit mass of the body by 1 °C. |
| The S.I. unit is JK-1 | S.I. unit is J kg-1K-1. |
(ii) Heat Capacity = Mass x Specific Heat Capacity
