When we start heating a cube of ice it changes its state without showing a rise in temperature as the heat gets used up in changing the state by overcoming the forces of attraction between the particles. As this heat energy is absorbed by ice without showing any rise in temperature, it is considered that it gets hidden into the contents of the beaker and is know as the latent(hidden) heat. therefore.......particles of water at 0 degree celcius have more energy that ice at 0 degree celcius..
