The three states of matter refer to the physical forms that matter can exist in: solid, liquid, and gas. In the solid state, particles are closely packed together and have a fixed shape and volume. In the liquid state, particles are more spread out and can move past each other, taking the shape of their container but maintaining a fixed volume. In the gas state, particles are far apart and move freely, filling the entire volume of their container.
