  • 1. BOYLES LAW
  • 2. SOLIDS, LIQUIDS AND GASES  How are the molecules/atoms arranged?  Solids: Tightly packed and vibrate  Liquids: Farther apart and can move past each other.  Gases: Very far apart and collide with one another randomly.
  • 3. KINETIC MOLECULAR THEORY  1) Gases particles are very small compared to distance separating them.  2) Gas molecules are in constant random motion and collide with one another and walls of container = gas pressure.  3) Collisions are elastic- no loss of total kinetic energy.  4) As temp increases so does the speed of the molecules and the average kinetic energy increases.
  • 4.  Kinetic Molecular theory
  • 5. BOYLE’S LAW: P-V RELATIONSHIPS  Gases can be compressed.  Decreased volume = increased pressure  Increased volume = decreased pressure  Why?  Pressure is the result of the collisions with the sides of the container.  If container (volume) becomes smaller the molecules collide with the sides of the container more often = increased pressure.
  • 6.  Marshmellow pals in a vacuum
  • 7. P1V1 = P2V2  What would the pressure in a can be if it can deliver 8000 ml of Helium at 1.3 atm and the can has a volume of 480 ml?
  • 8.  What would the volume of a can be if it can hold 5000 ml of a gas at 100 kPa and the pressure inside the can is 150 kPa?
