What happens to chemical potential energy as the particles become closer together?
It decreases.
What is it called when vaporization occurs only at the surface of the liquid?
Evaporation
What happens to potential energy as particles get farther apart?
It increases
What are always conserved during a change of state?
Matter and energy
What is the total kinetic and potential energy of an object measured by?
Thermal energy
What happens to kinetic energy when thermal energy is added?
Increases
