  16. Contrast Describe Explain Topic: Kinetic Molecular Theory & Boyle’s Law Date: 4/30/2013 Kinetic Molecular Theory of Gases: (Movement of Molecules) Gases are easily compressed. (They can take the shape of any container.) Gas particles move around randomly with no pattern. When gas particles collide, they do not lose energy. (They bump into each other and keep on moving.)  Because of these assumptions, predictions can be made about how gases will be affected by changes in temperature, pressure, and volume.
  17. Contrast Describe Explain Topic: Kinetic Molecular Theory & Boyle’s Law Date: 4/30/2013 Boyle’s Law = For a given amount of gas at a constant temperature, the VOLUME of the gas is inversely related to PRESSURE. So if: V ↑ = P ↓ V ↓ = P ↑ V α 1/P P α 1/V Constant Temperature Pressure Volume
  18. Topic: Kinetic Molecular Theory & Boyle’s LawDate: 4/30/2013 Variables & Units: P = Pressure (atm) (atm = atmospheres) V = Volume (L, mL) T = Temperature  constant Equation: P1V1 = P2V2
  19. Practice Problem A gas has an initial pressure of 5atm. The pressure was changed to 8atm and the volume became 10L. What was the starting volume of the gas? 1st Predict: If P↑, then V↓. 2nd Determine Variables: P1 = V1 = P2 = V2 = 3rd Calculate: P1V1 = P2V2 (5)(V1) = (8)(10) (5)V1 = 80 5 5 V1 = 80/5 V1 = 16L 5atm ? = x 8atm 10L
