The Kinetic Theory of Matter states that the particles that make up all matter are in perpetual motion. We know that a solid cannot change shape because its constituent particles are unable to change position. Explain how the particles that make up solid matter can be in perpetual motion if they do not change position.

Describe how the Kinetic Theory of Matter defines heat and how heat is affected by the rate of movement of the particles that make up matter.

1) Explain how the particles that make up solid matter can be in perpetual motion if they do not change position. Answer: they do not mov, just vibrate a bit more and move further apart. And as a result solid expand a bit.

2) How the Kinetic Theory of Matter defines heat. Answer: Heat is a form of energy that particles convert into kinetic energy. Adding a heat energy increases the kinetic energy of particles. This means that as a substance is heated - the particles vibrate faster and move further apart.
