Chemistry (please help!!)
posted by Celine on .
a stressed chemistry student is hyperventilating into a paper bag. The student stops to wip his brow after a few breaths, and the bag is at 5.7 KPa and the temperature in the lecture hall is 24 degrees 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 7.2KPa. The student panics, and runs out of the lecture hall... when he gest outside, the inflated paper bag explodes. What is the temperature outside?

My answer is 594 K... which is excessively high...

Do I not need to turn the temperature to Kelvin for the equation?? If I don't turn it to K I get 49 C... which is a more reasonable value... I left the other values with their same units... please someone answer...

(P1xV1)/T1 = (P2xV2)/T2
T2 = (P2xV2xT1)/(P1xV1) 
That's the equation I use use and I get 594 K... I think that's a really high value, is that answer right?
