This document discusses the different states of matter: solid, liquid, gas, plasma, and Bose-Einstein condensate. It explains that all states of matter are made up of atoms arranged in different patterns that determine the properties of each state. Solids have tightly packed atoms that do not change shape, while liquids have loosely packed atoms that take the shape of their container. Gases have very spread out atoms that fill their container. Plasmas are similar to gases but are made of ions and electrons. Bose-Einstein condensates form when atoms are cooled to near absolute zero and clump together.
