Change of state is caused by supply of heat to a substance causing its molecules to move faster.

There are three states of matter, these are;

It is possible for a substance to be transformed from one state of matter to the other when heat energy is supplied to the substance.

This heat energy causes the kinetic energy of the molecules of the substance to increase hence they vibrate faster and change from one physical state to another.

During a change in state, the motion of the particles changes. ... Particles in a liquid can side past each other, but particles in a solid can only move enough to vibrate. Removing energy from a liquid can cause it to change to a solid. Adding energy to a solid can cause it to change to a liquid.
