Quizplus · Accepted Answer

Phase changes involve the transition of matter from one state (e.g. solid, liquid, gas) to another through the addition or removal of energy. When matter goes from a higher energy state to a lower energy state (such as from gas to liquid or liquid to solid), energy is released in the form of heat.
