Question

what change take place indside the matter when it state change

Answer 1

intermolecular space changes and so does intermolecular force, kinetic energy

Answer 2

If the change exist from solid to liquid the intermolecular force of attraction , intermolecular space,potential energy and kinetic energy becomes moderate ......and in liquid to gas intermolecular force of attraction does not exist, intermolecular space becomes very high , potential energy becomes very less and kinetic energy becomes very high
