The quantity of heat energy absorbed by a body depends on three factors :
(i)Mass of the body - The amount of heat energy required is directly proportional to the mass of the substance.
(ii)Nature of material of the body - The amount of heat energy required depends on the nature on the substance and it is expressed in terms of its specific heat capacity c.
(iii)Rise in temperature of the body - The amount of heat energy required is directly proportional to the rise in temperature.
