1. THE KINETIC MOLECULAR THEORY OF MATTER

2. 1. ALL MATTER IS MADE UP OF ATOMS  Solids are joined together tightly and maintain a constant shape and volume  Liquids are joined together loosely and maintain their shape but not their volume  Gases are not joined and do not maintain their shape or volume

3. 2. MOLECULES ARE IN CONSTANT MOTION 1. Gas molecules are in constant random motion 2. Liquid molecules can rotate and vibrate 3. Solid molecules can only vibrate

5. 3. COLLISION BETWEEN MOLECULES TRANSFERS ENERGY Similar to a newton’s cradle, a collision between the first two balls transfers energy to the next ones causing them to move as well

6. 4. THERMAL ENERGY (HEAT) INCREASES MOLECULAR MOTION  The amount of energy that a particle has is directly related to the temperature

7. 5. MOLECULES IN GASES DO NOT EXERT LARGE FORCES ON ONE ANOTHER UNLESS THEY COLLIDE

8. PHASE CHANGES BETWEEN MATTER  All matter can move from one state to another

9. PHASE CHANGE TERMS Start from:Change to:Name solidliquidmelting liquidsolidfreezing liquidgasboiling gasliquidcondensation solid gas (skipping liquid phase) sublimation

10. ASSIGNMENT You will now apply what you have learned (and will learn) to create a product that describes the Kinetic Molecular Theory of Motion
