Question:

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{eq}^\circ {/eq} C. The bag is 0.75 L full. The student then goes at it again, and completely fills the bag with air to 1.2 L and 7.2 KPa. The student panics, and runs out of the lecture hall, when he gets outside, the inflated paper bag explodes. What is the temperature outside?
