When you add heat to ice at zero degrees celsius the energy causes the movement of ice molecules to increase. When the ice molecules get enough energy, their movement causes them to break free of one another and change to a liquidform.When more heat is added the water molecules absorb that energy and move faster, causing an energy and move faster, causing an increase in temperature (an increase in average energy). When the water molecules absorb enough energy (at about a hundred degrees celsius) they are able to change state again froma liquid to a gas (steam). i dont know weather this the answer you are looking for or not if not i susjest you try and google it
