P ~ 1/V Boyle’s Law: P 1 V 1 = P 2 V 2 If the volume of a gas is constrained to a smaller container, how much force does it exert?
Decrease volume Æ more collisions V 1 V 2 P 1 P 1 V 1 = P 2 V 2 Relationship between volume and pressure.

• Ex. 1 A sample of gas occupies 21 liters at a pressure of 2.2 atm. What would be the volume if the pressure was increased to 6.2 atm? • Ex. 2 A sample of O 2 occupies 10.0 L at 785 torr. At what pressure would it occupy 14.5 L?
Charle’s Law: V 1 /T 1 = V 2 / T 2 If the temperature of gas is increased, how will its volume respond (if the pressure is kept constant)?

Combined Gas Law (Boyle and Charle’s) P 1 V 1 = P 2 V 2 T 1 T 2
Re-cap of Gases: Boyle’s Law: Charles’s Law: P 1 V 1 = P 2 V 2 V 1 /T 1 = V 2 / T 2 P 1 V 1 = P 2 V 2 T 1 T 2 1) Gas equations should make sense: volume, pressure, temperature 2) Watch your units! (K, L, atm)
