A weather balloon is filled with helium that occupies a volume of 4.33 104 L at 0.995 atm and 32.0°C. After it is released, it rises to a location where the pressure is 0.720 atm and the temperature is -10.2°C. What is the volume of the balloon at that new location?

Answer 1

(P1V1/T1) = (P2V2/T2)
Remember T must be in Kelvin.

Answer 2

so is it .995 times 4.33 divided by 32 +273 =.720 V2 / -10.2 + 273
