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.
