### The Gas Laws

1. 1. The Gas Laws<br />
2. 2. Measurable Properties of Gases<br />P= pressure<br />T= temperature<br />V= volume<br />
3. 3. Measurable Properties of Gases<br />P T V<br />
4. 4. Boyle’s Law<br />P1V1 = P2V2<br />When temperature is constant, PRESSURE and VOLUME have an Inverse Relationship<br />
5. 5. Boyle’s Law example<br />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?<br />
6. 6. Charles’s Law<br />V1/T1 = V2/T2<br />When pressure is constant, VOLUME and TEMPERATURE have a Direct Relationship<br />
7. 7. Charles’s Lawexample<br />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? <br />
8. 8. Gay-Lussac’s Law<br />P1/T1 = P2/T2<br />When volume is constant, PRESSURE and TEMPERATURE have a Direct Relationship<br />http://www.videojug.com/film/how-to-suck-an-egg-into-a-bottle<br />
9. 9. Gay-Lussac’s Lawexample<br />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. <br />
