What other states of matter can plasma exist in?
Plasma is the state of matter when matter is highly energized and loses electrons, like in a star, bolt of lightning or a welding arc. Consider a welding arc — the current flow creates an arc between the rod and the base metal. The material in the arc is “plasma” state of matter but is still metallic elements so when it strikes and bonds with the base metal it becomes a liquid and then a solid. So yes, matter can become plasma and then return to one of the other three states of matter.
