1. Gas Laws Summary

3. States of Matter & Kinetic Energy Low KEHigh KE

4. Gas Phase Molecules are in constant random motion, colliding with objects, exerting a Force on those objects

5. Gas Pressure Gas Pressure is the force of the gas particles colliding with the walls of its container

6. Gas Law Variables 1.Number of Molecules 2.Pressure 3.Volume 4.Temperature

7. Pressure vs. Volume Pressure vs. Temperature Volume vs. TemperaturePressure vs. Number of Molecules

8. Boyle's Law (P & V) Decreases Volume Increase Pressure More Collisions Inverse Relationship Hi Vol = Lo Pressure Lo Vol = Hi Pressure Constants # Molecules Temperature (energy)

9. Lussac's Law (P & T) Constants - Volume & # Molecules Decrease Temp Decrease Pressure Decreases KE *Less Collisions* Increase Temp Increase Pressure Increases KE *More Collisions* Direct Relationship Hi Temp = Hi Pressure Lo Temp = Lo Pressure

10. Charles' Law (V & T) Increase Temp Increase Volume Increases KE *More Collisions* Direct Relationship Hi Temp = Hi Volume Lo Temp = Lo Volume Constants Pressure # Molecules

11. Pressure vs Molecules Increase Number of Molecules Increase Pressure Increases Collisions Direct Relationship Lots Molecules = Hi Pressure Low Molecules = Lo Pressure Constants Temperature Volume
