# Question: A sealed balloon is filled with 1 00 L of helium

A sealed balloon is filled with 1.00 L of helium at 23oC and 1.00 atm. The balloon rises to a point in the atmosphere where the pressure is 220. torr and the temperature is 231oC. What is the change in the volume of the balloon as it ascends from 1.00 atm to a pressure of 220. torr?
