1. If I initially have a gas at a pressure of 12 atm, a volume of 23 L, and
a temperature of 200K, and then I raise the pressure to 14 atms and
increase the volume to 27 L, what is the new temperature of the gas?
2. A gas takes up a volume of 17 L, has a pressure of 2.3 atms, and
temperature of 299 K. If the temperature is raised to 350 K and the
pressure is lowered to 1.5 atms, what is the new volume of the gas?
3. A helium-filled balloon at sea level has a volume of 2.1 L at 0.998 atm
and 36C. If it is released and rises to an elevation at which the
pressure is 0.900 atm and the temperature is 28C, what will be the
new volume?
4. At 0.00C and 1.00 atm pressure, a sample of gas occupies 30.0 mL. If
the temperature is increased to 30.0C and the entire gas sample is
transferred to a 20.0 mL container, what will be the gas pressure
inside the container?
5. A sample of air in a syringe exerts a pressure of 1.02 atm at a
temperature of 22.0C. The syringe is placed in a boiling water bath
at 100.0C. The pressure of the air is increased to 1.23 atm by
pushing the plunger in, which reduces the volume to 0.224 mL. what
was the original volume of gas in the bottle?
