It is the sum of the (related to temperature) and the potential energy (related to state/distance between particles). Specific Latent Heat

Particles are close together but can move past each other in an irregular arrangement.

Boiling or condensing. Formula: (Energy = mass Specific Latent Heat). Gas Pressure and Temperature

Solids are generally the most dense, followed by liquids, then gases.
