A helium balloon is filled to a volume of 2.88 x 10^3L at 722 mm Hg and 19 degrees Celcius. When the balloon is released, it rises to an altitude where the pressure and temperature are 339 mm Hg and -55vC, respectively. What is the volume of the balloon?
(P1V1/T1) = (P2V2/T2)
Don't forget T is in Kelvin.
Note the correct spelling of celsius.
