What happens to the size of molecules and what happens to the total mass of the sample when heat is applied to an ice cube in a closed container has to be explained. Concept Introduction : Melting is a process in which solid transforms into liquid and boiling is a process in which liquid transforms into vapor phase. For both these process to happen heat has to be applied to the substance under consideration. The size of the atoms or molecule of a substance does not change when heat is applied. The volume alone increases if heat is supplied. Kinetic energy of the gas molecules also increases. To Explain: When heat is applied to an ice cube, what happens to size of the molecules and what happens to the total mass of the sample has to be explained.
