7. 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.

8. 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.
