Physics
Heat capacity of a body is:
- the energy needed to melt the body without the change in its temperature.
- the energy needed to raise the temperature of the body by 1°C
- the increase in the volume of the body when its temperature increases by 1°C
- the total amount of internal energy that is constant.

Answer
the energy needed to raise the temperature of the body by 1°C
Reason — The term heat capacity of a body is the amount of heat energy required to raise it's temperature by 1° C (or 1 K). The S.I. unit of heat capacity is joule per kelvin (J K-1)
