Charles' Gas Law Practice Questions (Gap-fill exercise)
Fill in all the gaps, then press "Check" to check your answers.
1. The initial temperature of a gas is 20C. Following compression of a gas from 2 L to 1L, the new temperature is
K.
2. Supposing one begins with 600 ml of isoflurane at 20 C. The volume at 60 C would be
ml.
3. Halothane occupies a volume of 900 ml at 27C. The volume occupied at 132 C is
ml.
4. A gas starts out at a volume of 60 ml at 33C and is then cools to 5 C. The new volume would be
ml.
5. At 17 C, a balloon of hydrogen gas occupies 300 ml. However, upon cooling to 10C, the volume occupied is only
ml.
6. A syringe contains 56.05 ml of a gas at a temperature of 315.1K. If the temperature were increased to 380.5K, the new volume in the syringe would be
mls.
7. This is a question in part about the meaning of STP (standard temperature and pressure). If a gas occupied 1L at STP, the volume at 150C would be
L.
8. Suppose a gas exhibits a volume of 6L at 225C. The volume of the gas at a temperature of 150C would be
L.
9. Helium at 225 C exhibits a volume of 400 ml. The volume of this gas at 127 C would be
mls.
10. Some gas has a volume of 8 L when the temperature is 210C, but the volume would be less at -23 C. The new volume at the colder temperature is
L
