Question

Name two factors on which the heat energy liberated by a body depend.

Answer 1

Heat energy by a body depends on the surface area of the body $A$ as well as the temperature of body $T$.

According to Stefan's law, rate of heat energy radiated by a body is given by $P=\sigma Ae{T}^4$

Thus more is the temperature of body, more is the heat radiated. Also mores is the surface area of body, more is the heat radiated.
