How do changes of state relate to the kinetic theory?

As the kinetic energy of the matter changes, the matter changes state.

According to the Kinetic-Molecular Theory, changes of the state of matter occur when energy is added or removed from a substance. The addition of energy makes particles move more, pushing them apart and weakening the bonds between them. Removing energy makes particle movement slow down, re-forming the bonds.
