1. V1 = 4.6 L V2 = 330 L P1 = 1.18 atm P2 = ? atm P1V1 = P2V2
The pressure of air on a 4.6 L container is 1.18 atm. What is the new pressure if the sample is transferred to a 330 L container?
V1 = 4.6 L
V2 = 330 L
P1 = 1.18 atm
P2 = ? atm
P1V1 = P2V2
1.18 x 4.6 = P2 x 330
1.18 atm x 4.6 L = P2= atm

2. V1 = 5.3 L V2 = ? L T1 = 65oC = 338 K T2 = 42oC = 315 K V1 = V2 T1 T2
A balloon has a volume of 5.3 L and is filled at a temperature of 65°C. What volume will the balloon occupy at a temperature of 42°C? P?
V1 = 5.3 L
V2 = ? L
T1 = 65oC = 338 K
T2 = 42oC = 315 K

3. T1= 25oC = 298 K T2= -10.0oC = 263 K P1 = 5.00 atm P2 = ? atm P1 = P2
The pressure of the oxygen gas inside a canister is 5.00 atm at 25°C. The canister is located at a camp high on Mount Everest. If the temperature falls to -10.0°C, what is the new pressure inside the canister?
T1= 25oC = 298 K
T2= -10.0oC = 263 K
P1 = 5.00 atm
P2 = ? atm
P1 = P2

5.00 atm x 263 K = P2= 4.41 atm
298 K

4. A gas at 110 kPa and 30.0°C fills a flexible container with an initial volume of 2.00 L. If the temperature is raised to 80.0°C and the pressure increases to 440 kPa, what is the new volume?
V1 = 2.00 L
V2 = ? L
T1= 30.0oC = 303 K
T2 = 80.0oC = 353 K
P1 = 110 kPa
P2 = 440 kPa
P1V1 = P2V2
T T2
110 x 2.00 = 440 x V2

5. V1 = 50.0 mL V2 = ? mL T1= 23.0oC = 296.0 K T2 = 273 K P2 = 1 atm
A gas has a volume of 50.0 ml at 0.90 atm and 23.0°C. How much is the gas volume at STP?
V1 = 50.0 mL
V2 = ? mL
T1= 23.0oC = K
T2 = 273 K
P1 = 0.90 atm
P2 = 1 atm
P1V1 = P2V2
