What is the Particle Theory of Matter?

The Particle Theory of Matter states that:1. Matter is comprised of tiny particles; i.e.: atoms and molecules.2. Particles of matter are in constant motion.3. Particles of matter are held together by strong electrical forces.4. There are spaces between the particles that are very large compared to the particles themselves.5. Each substance has particles that are different from the particles of other substances.6. Temperature affects the speed of the particles. The higher the temperature is, the faster the particles will move.
