1. Chapter 15 Kinetic Molecular Theory

2. Some Amazing Things

3. Kinetic Theory

4. All matter is composed of tiny particles.

5. Kinetic Theory All matter is composed of tiny particles –Atoms

6. Kinetic Theory All matter is composed of tiny particles –Atoms –Molecules

7. Kinetic Theory All matter is composed of tiny particles –Atoms –Molecules –Ions

8. Kinetic Theory These tiny particles are in constant motion.

9. Kinetic Theory Collisions between moving particles are perfectly elastic. –In an elastic collision there is no net change in kinetic energy.

10. Pressure Pressure depends on two factors 1.Force 2.Area Pressure = Force Area

11. Examples of Pressure

12. Gas Pressure

13. Temperature How hot or cold Average kinetic energy

14. Absolute Zero K = °C + 273

15. How do we lower temperature? We slow down the particles.

16. Kinetic Energy KE = ½ mv 2 When considering kinetic energy we must consider two factors. 1.Mass 2.Velocity
