  1. State the Following Laws • Boyle’s Law • Charles’ Law • Gay Lussac’s Law • Dalton’s Law • Graham’s Law

  2. Drill: • Calculate the volume at STP of CO2 released when 23.4 g of aluminum carbonate is decomposed 75 % through heat

  3. AP Test Changes • No Choices in Problems • Only 3 reactions with predicting products • Balance rxns • No choices • Explain rxns

  4. Kinetic Theory

  5. All matter is made up of tiny particles • The particles are in constant motion • All collisions are elastic

  6. Pressure

  7. Force per unit area • Caused by collisions against a surface • Gas measured in pressure

  8. Units of Pressure • kPa: kilopascal (Std Unit) • Pascal: newton/sq. meter • Atmosphere (Atm): • mm Hg:

  9. Standard Pressure • 101.3 kPa (to be changed) • 1.00 Atm • 760 mm Hg or Torrs • 30.0 inches Hg • 1013 millibars

  10. Gas Laws

  11. Boyle’s Law

  12. The pressure & volume of a gas at constant temperature are inversely proportioned P1V1 = P2V2 = K

  13. Charles’ Law

  14. The volume and temperature of a gas at constant pressure are directly proportioned V1/T1 = V2/T2 = K

  15. Guy Lussac’s Law

  16. The Pressure and temperature of a gas at constant volume are directly proportioned P1/T1 = P2/T2 = K
