A flexible weather balloon contains helium gas at a volume of 855 L. Initially, the balloon is at sea level, where the temperature is 25oC and the barometric pressure is 0.947 atm. The balloon then rises to an altitude of 5500 ft, where the pressure is 0.783 atm and the temperature is 15oC. What is the change in the volume of the balloon as it ascends from sea level to 5500?
