Boyle’s <strong>Law</strong><br />
1. A sample of carbon dioxide occupies a volume of 3.50 litters at 125 kPa pressure. What pressure<br />
would the gas exert if the volume was decreased to 2.00 liters<br />
2. Fluorine gas exerts a pressure of 900 torr. When the pressure is changed to 1.50 atm, its volume<br />
is 250 ml. What was the original volume<br />
3. A 1.00L sample of a gas at standard temperature and pressure is compressed to 473 ml. What is<br />
the new pressure of the gas<br />
Charles’ <strong>Law</strong><br />
4. A sample of argon gas is cooled and its volume went from 380 ml to 250 ml. If its final<br />
temperature was -55 o C, what was its original temperature<br />
5. A sample of nitrogen occupies a volume of 250 ml at 25 o C. What volume will it occupy at 95 o C<br />
6. Hot air balloons rise because the hot air inside the balloon is less dense than the cooler air<br />
outside. Calculate the volume an air sample will occupy inside a balloon at 43.0 o C if it occupies<br />
2.50 L at the outside temperature of 22.0 o C, assuming the pressure is the same at both<br />
locations.<br />
Gay Lussa’s <strong>Law</strong><br />
7. The pressure on a sample of gas is 200.0 torr at a temperature of 25.0 o C. What is the new<br />
pressure if the temperature rises to 100 o C
8. What is the pressure of a fixed volume of a gas at 30.0 o C if it has a pressure of 1.1 atm at 15.0<br />
o C<br />
9. The pressure in a bicycle tire is 1.34 atm at 33.0 o C. At what temperature will the pressure<br />
inside the tire be 1.60 atm Volume is constant.<br />
Combined Gas <strong>Law</strong><br />
10. A sample of nitrogen gas is stored in a 500.0ml flask at 108 kPa and 10.0 o C. The gas is<br />
transferred to a 750.0 ml flask at 21.0 o C. What is the pressure of nitrogen in the flask<br />
11. A toy balloon has an internal pressure of 1.05 atm and a volume of 5.0 L. If the temperature<br />
where the balloon is released is 20 o C, what will happen to the volume when the balloon rises to an<br />
altitude where the pressure is 0.65 atm and the temperature is -15 o C<br />
12. A weather balloon is filled with helium that occupies a volume of 5.00 x 10 4 L at 0.995 atm and<br />
32.0 o C. After it is released, it rises to a location where the pressure is 0.720 atm and the<br />
temperature is -12.0 o C. What is the volume of the balloon at that new location<br />
Avogadro’s Principle<br />
13. Carbon monoxide, CO, is a product of incomplete combustion of fuels. Find the volume that 42 g<br />
of carbon monoxide gas occupies at STP.<br />
14. Calculate the volume that 0.540 mol of propane occupies at STP.<br />
15. Calculate the volume that 4.5 kg of ethylene gas (C 2 H 4 ) will occupy at STP.
