A stressed chemistry student is hyperventilating into a paper bag. The student stops to wipe his brow after a few breaths, and the bag is at 5.7 KPa and the temperature in the lecture hall is 24 °C. The bag is 0.75L full. The student then goes at it again, and completely fills the bag with air to 1.2L and 7.2KPa. The student panics, and runs out of the lecture hall...when he gets outside, the inflated paper bag explodes. What is the temperature outside?

    What exactly does 0.75L full mean? The bag is 3/4 full or what?

    No I don't think so because after the student goes at it again it is filled to 1.2L and it can't be more than completely filled. I think I am probably supposed to use V1/T1=V2/T2 or P1V1/T1= P2V2/T2. I just do not know because I feel like I have two volumes.
