Ahot-air balloon is filled with air to a volume of at 750. torr and 21°c. the air in the balloon is then heated to 58°c, causing the balloon to expand to a volume of . what is the ratio of the number of moles of air in the heated balloon to the original number of moles of air in the balloon? (hint: openings in the balloon allow air to flow in and out. thus the pressure in the balloon is always the same as that of the atmosphere.) ratio = 1
