As energy in the form of heat is added to an ice cube, it begins to melt. What causes melting.

• Heat causes the molecules to expanded and forces them apart.

• Heat removes thermal energy from the ice cube and causes it to become liquid water.

• Adding energy causes the bonds between the hydrogen and oxygen in the ice cube to break.

• The transfer of thermal energy to the ice cube causes its molecules to move faster.
