1. The Gas Laws

2. Measurable Properties of Gases P= pressure T= temperature V= volume

3. Measurable Properties of Gases P T V

4. Boyle’s Law P1V1 = P2V2 When temperature is constant, PRESSURE and VOLUME have an Inverse Relationship

5. Boyle’s Law example The volume of air in the marshmallows blaster is 450 mL. The pressure is 1.00 atm. If I decrease the volume to 50 mL, what will the new pressure be?

6. Charles’s Law V1/T1 = V2/T2 When pressure is constant, VOLUME and TEMPERATURE have a Direct Relationship

7. Charles’s Lawexample A Balloon is inflated to 300 mL at 20° C. It is placed in a warm water bath and heated to 70° C. What is the new volume of the balloon?

8. Gay-Lussac’s Law P1/T1 = P2/T2 When volume is constant, PRESSURE and TEMPERATURE have a Direct Relationship http://www.videojug.com/film/how-to-suck-an-egg-into-a-bottle

9. Gay-Lussac’s Lawexample The pressure inside a truck tire is 1.25 atm and the temperature is 50° C. What is the pressure in the tire when the temperature is 10° C.
