1. Notes 3-2 “The Gas Laws”

2. What is pressure? N/m 2 Pa KPa

4. Temperature Greater Temp = Greater Pressure Energy? Volume? Collisions?

5. Volume ▼volume = ▲pressure ▲volume = ▼pressure If the temp. and # of particles are held constant

6. Number of Particles ▲particles = ▲collisions = ▲pressure ▼particles = ▼collisions = ▼pressure Charles’s Law Volume ▲ at the same rate as Temp. V 1 = V 2 T 1 T 2

7. Temp in Kelvin Boyle’s Law volume is inversely proportional to its pressure. P 1 V 1 = P 2 V 2

8. The Combined Gas Law Relates temp, volume and pressure P 1 V 1 = P 2 V 2 T 1 T 2 Look at the 3 examples on p. 80
