Energy and Temperature

As we heat our substance, the molecules move faster and faster. Occasionally some of them acquire a kinetic energy larger than the potential energy barrier and break away. We know that water in contact with melting ice gets colder: the kinetic energy of the water molecules is transferred to the potential energy of those ice molecules that are separating themselves from the ice crystal and moving into the liquid.

At very high temperatures, all the molecules separate from each other.
