Vedclass · Answer

(B) The temperature of a substance remains constant at its melting and boiling points until all the substance melts or boils because the heat supplied is continuously used up in changing the state of the substance by overcoming the forces of attraction between the particles.This heat energy,which is absorbed without showing any rise in temperature,is known as latent heat of fusion or latent heat of vaporization.
