Matter can change states between solid, liquid, and gas. Water is used as an example, changing between ice, liquid water, and water vapor through the processes of melting, evaporation, and condensation. Evaporation occurs when liquid water is heated and changes into gas water vapor, while condensation is when water vapor cools and changes back into liquid water.
