1. ____________

1. A gas takes up a volume of 18 L, has a pressure of 2.5 atm, and a temperature of 290 K. If I raise the temperature to 359 K and lower the pressure to 1.6 atm, what is the new volume of the gas?

2. ____________

2. I have an unknown volume of gas at a pressure of 0.54 atm and a temperature of 335 K. If I raise the pressure to 1.20 atm, decrease the temperature to 330 K, and measure the final volume to be 45 L, what was the initial volume of the gas?

3. ____________

3. If I have 3.9 L of gas at a pressure of 6 atm and a temperature of 50 0C, what will be the temperature of the gas if I decrease the volume of the gas to 3.4 L and decrease the pressure to 4 atm?

4. ____________ 16. ______________

4. A gas has a volume of 5.0 L at 50kPa of pressure. What happens to the volume when the pressure is increased to 125kPa and the temperature stays the same?

5. ____________

XC. ____________

5. Gas stored in a tank at 273K has a pressure of 388kPa. The safe limit for the pressure is 825kPa. At what temperature will the gas reach this pressure?

XC. At 10 C, the gas in a cylinder has a volume of 0.250L. The gas is allowed to expand to 0.285 L. What must the final temperature be for the pressure to remain constant? (K= C + 273)
