        Thermal energy is the total potential and kinetic   What is the Effect of Temperature and Energy on

        You can change an object’s state of matter by adding  All matter has thermal energy, and thermal
        or removing thermal energy.                          energy is the sum of potential and kinetic
                                                                              energy.
        If enough thermal energy is added or removed from
        an object, a change of state can occur.

                                                           Vaporization

                                                           is the change in state of a liquid into a gas.
