This is the amount of energy required to change the state of 1kg of a substance with no change in temperature. Melting or freezing.
Particles are in a fixed, regular arrangement and vibrate around fixed positions.
Particles are far apart and move randomly at high speeds. Changes of State Physical changes (reversible) rather than chemical changes. Mass is conserved during a change of state.
