Balloon is filled to a volume
« on: October 24, 2009, 06:45:31 PM »
A balloon is filled to a volume of 69.0 mL at a temperature of 24.0oC.
The balloon is then heated up at constant pressure to a temperature of 85.0oC.
What is the final volume of this balloon, in liters?

V1/T1 = V2/T2 <---- and were trying to solve for v2
V1/(T1)(T2) = V2

69.0ml x 0.001 L = .069L

24.0oC + 273 = 297
85.0oC + 273 = 358

(.069)/ (297) (358) = .0832

I am pretty sure i did this right, but the answers do not match, when i enter .0832

Can someone explain what I'm doing wrong without giving away the answer, thanks

you might look at your algebra
does
V1/T1 = V2/T2
solve to
V1/(T1)(T2) = V2
