Gas Laws

Gas Laws: Boyle and Charles
Boyle P1V1=P2V2
Charles V1/T1 = V2/T2
Mr. Brown
Part One: Conceptual
Apply Boyle’s Law to each scenario. The following volume values indicate what the gas occupies. Answer
the questions as “if the pressure exerted on the container….then the container volume would be ….
Liters.
Gas Volume
If the pressure…
1. 1 Liter
doubled…
2. 2 Liters
were halved…
3. 3 Liters
quadrupled…
4. 4 Liters
decreased by a third…
then the volume would be
Apply Boyle’s Law to each scenario. Answer the questions as “if the volume changed this much on the
container….then the pressure would change by this much.
If the volume changed by…
5. increased ten times
6.decreased five times
7. decreased by half
8. tripled
Part Two: Definitions
9. Define Boyle’s Law in words:
10. Define Charles’s Law in words:
then if pressure would change by…
Part Three: Calculations
11. A sample of oxygen gas has a volume of 150.0 mL when its pressure is 0.947 atm. What will the
volume of the gas be at a pressure of 0.987 atm if the temperature remains constant?
12. A balloon filled with helium gas has a volume of 500 mL at a pressure of 1 atm. The balloon is
released and reaches an altitude of 6.5 km, where the pressure is 0.5 atm. If the temperature has
remained the same, what volume does the gas occupy at this height?
13. A sample of neon gas occupies a volume of 752 mL at 25°C. What volume will the gas occupy at 50°C
if the pressure remains constant?
14. A sample of neon gas has a volume of 752 mL at 25.0 °C. What will the volume at 100.0 °C be if
pressure is constant?
15. A sample of nitrogen gas is contained in a piston with a freely moving cylinder. At 0.0 °C, the volume
of the gas is 375 mL. To what temperature must the gas be heated to occupy a volume of 500.0 mL?
