There are five states of matter: solid, liquid, gas, plasma, and Bose-Einstein condensate. All states are made up of atoms that have different patterns depending on the state. A Bose-Einstein condensate forms when atoms clump together at extremely cold temperatures. Solids have tightly packed molecules that hold their shape, while liquids take the shape of their container but have less tightly packed molecules than solids. Gases have very spread out atoms and can fill any container. Plasma consists of free electrons and ions found mostly in atmospheres.
