Combined Gas Law Name: ___________________ Date: ____________ P1 x V1 = P2 x V2 T1 T2 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 36C. If it is released and rises to an elevation at which the pressure is 0.900 atm and the temperature is 28C, what will be the new volume? 4. At 0.00C and 1.00 atm pressure, a sample of gas occupies 30.0 mL. If the temperature is increased to 30.0C 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 22.0C. The syringe is placed in a boiling water bath at 100.0C. 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?
