A 1.00 mL sample of N2(g) at 36.2 oC and 2.14 atm is heated to 37.8 oC, and the pressure changed to 1.02 atm. What volume does the gas occupy at this final temperature and pressure?

Answer 1

A cylinder contains a gas at 5.25 atm pressure. When the gas is allowed to
expand to a final volume of 12.5 L, the pressure drops to 1.85 atm. What was
the original volume of the gas?

Answer 2

For the first question, use P1V1/T1 = P2V2/T2 Remember to use kelvin for T; i.e., Kelvin = 273 + C.
For #2 use P1V1 = P2V2
