Changes in matter are due to either the absorption of energy or the release of energy. A change from solid, for example ice, requires heat (aka energy) to become a liquid, and more to become a gas. The "cooling off" of the molecules, or the release of energy, however, causes changing from a gas to a liquid.
The process in which energy is given off is called an exothermic change. The energy released can be in the form of heat, light, electricity, or sound

What type of energy is given off with the heat energy?
Endothermic Reaction. Exothermic is a chemical reaction in which energy must be provided.
When a substance loses energy, it becomes more compact. A gas would turn to liquid and a liquid would turn to solid.
Exothermic
