Because there is a freezing point, a boiling point so Solids can change into liquids and liquids can change into gases and all over again!!!!!!!!!!!!!!
Solids changing to liquids are melting Liquids changing to solids are freezing Solids changing to gas are subliming Liquids changing to gas are boiling Gases changing to liquids are condensing.
Gases have the highest kinetic energy, followed by liquids, and then solids. -apex
Solids have the lowers and gases the highest kinetic energy. Liquids are in the middle.
The kinetic energy is lowest in solids, higher in liquids, and highest in gases.
The kinetic energy in liquids is greater than that in solids because the molecules in solids are more closely packed together than in liquids such that liquids can freely move about within the containing vessel.
Heating.
The common denominator would be the kinetic energy of the particles making up the solids, liquids, and gases.

Liquids do, but solids do not.
