Explanation:
Answer:
The kinetic theory of matter explains that all matter is made of particles which are constantly moving/have energy. The energy varies depending on the temperature of the matter, therefore determining if the matter is solid, liquid, or gas. When the energy of a particle is increased or decreased, a phase change can occur.
On a molecular level there is a lot of movement which in turn is the reason why heat is generated.
