9 In one city, a balloon with a volume of 6.0 L is filled with air at 101 kPa pressure. The balloon is then taken to a second city at a much higher altitude. At this second city, atmospheric pressure is only 91 kPa. If the temperature is the same in both places, what will be the new volume of the balloon? Students type their answers here
