3 of 5 points in the Kinetic Molecular Theory:
1. Gases consist of tiny particles, atoms or molecules. 2. The size of an individual gas particle is assumed to be zero. 3. Particles have inconsistent random movement which causes them to collide with the sides of jar causing pressure. 4. particles do not attract nor repel each other. 5. the Hotter a gas the faster the particles are moving.
