7. A gas takes up a volume of 15 liters, has a pressure of 3.3 atm, and a temperature of 299 K. If I raise the
temperature to 350 K and lower the pressure to 1050 mmHg, what is the new volume of the gas?
8. I have an unknown volume of gas held at a temperature of 115 K in a container with a pressure of 60.0
atm. If by increasing the temperature to 225 K and decreasing the pressure to 30.0 atm causes the volume
of the gas to be 25 liters, how many liters of gas did I start with?
9. A gas has a temperature of 14oC, and a volume of 5.5 liters. If the temperature is raised to 29oC and the
pressure is not changed, what is the new volume of the gas?
10. A gas that has a volume of 28 liters, a temperature of 65oC, and an unknown pressure has its volume
increased to 36 liters and its temperature decreased to 35oC. If I measure the pressure after the change to
be 2.0 atm, what was the original pressure of the gas?
