Heyyy,

Molecules have two types of energy, bond energy and kinetic energy. Now we all know that kinetic energy is related to to temperature. During phase change (when laten heat is absorbed or released) the bonds break or form, this changes the bond energy of the molecule NOT kinetic energy. Since Ke doesn't change, temp too doesn't change.

Ah very nice, so since there is no change in kinetic energy there is no change in temperature.
