Explanation:
the kinetic theory of matter can be used to explain how solids, liquids and gases are interchangeable as a result of increase or decrease in heat energy. when an object is heated the motion of the particles increases as the particles become more energetic. if it is cooled the motion of the particles decreases as they lose energy.
