Brian -. I don t quite understand what you mean by energy states, but here s what I do know about solids, liquids, and gases. Solids are things where the molecules are all stuck together very tightly in a regular pattern. The molecules move around very little and have a low amount of energy. If you add energy by heating it up, the molecules will move around faster and slide against each other, and it will be a liquid. Molecules in a liquid have more energy than molecules in a solid.
