Changes of State In order to change to a different state of matter you must increase or decrease the temperature. Temperature measures the amount of energy of a certain amount of molecules. The higher the temperature, the faster the molecules move.

Changes of State Melting point – the temperature at which water changes from solid to liquid. Boiling point – the temperature at which water changes from liquid to a gas.
