heat is absorbed by the body but its temperature does not rise.

it is when the body is changing its state. the body uses this heat called the latent heat because it is hidden. there are two types of latent heats - latent of fusion (melting) and latent heat of vaporisation. rate me............

heat is used to break or loosen the bonds b/w particles .. so in that situation .. heat is absorbed but temp doesnot rise ...

It is called as latent heat

EXAMPLE: WATER

water has latent heat of about 330kJ/kg. it will liberate that much heat and become ice at 0*C.

in the same way when ice is heated it will absorb 330kJ/kg of heat and will become water.

Change in state leads to absorption of heat but at constant temperature and this heat is known as latent heat of fusion or vaporization depending on change in state from solid to liquid or from liquid to vapor.

As many have already discussed..i would just like to add a thing to it. Temperature is the measure of average kinetic energies of the particles forming any body..during a phase change all the heat absorbed is used to loosen the bonds at atomic levels to bring about a change in the so called PHASE of the body..Here, if it is supplied more heat than the latent amount its temprature will surely increase..

apart from latent heat,deu to expansion this may happen
