1. If I inhale 3.5 liters of gas at a temperature of 190 C and it heats to a temperature of 580 C in my lungs, what is the new volume of the gas?

2. If 1.50 L of a gas is at standard temperature and pressure is compressed to 556 mL, what is the new pressure of the gas in atm (hint, temperature stays the same)?

3. If I have a 125 mL bag at a temperature of 21 0C, and I leave it in my car with a temperature of 300 C, what will the new volume, in mL, of the bag be?

4. I have an unknown volume of gas at a pressure of 1.5 atm and a temperature of 315 K. If I raise the pressure to 1.9 atm, decrease the temperature to 300 K, and measure the final volume to be 34 liters, what was the initial volume of the gas?

5. An experimental research submarine with a volume of 17,000 liters has an internal pressure of 1.5 atm. If the pressure of the ocean breaks the submarine forming a bubble with a pressure of 245 atm pushing on it, how big will that bubble be in liters?

6. If I have an unknown quantity of gas held at a temperature of 395 K in a container with a volume of 8.5 liters and a pressure of 2.4 atm, how many moles of gas are present?

7. A gas that has a volume of 13 liters, a temperature of 25 0C, and an unknown pressure has its volume increased to 27 liters and its temperature decreased to 15 0C. If I measure the pressure after the change to be 1.3 atm, what was the original pressure of the gas?
