Answer 2

There is no rise in temperature of a substance because when heat is supplied that heat is used up by particles of substance to change it's state. Eg. to melt ice cubes, we supply heat energy and those heat energy is used up by molecules of ice to change into liquid. Thus heat energy is completely used by molecules of substance to change its state rather than to rise temperature... This heat energy is called 'Latent Heat of Energy'.
