    Consider an 18 m diameter hot air balloon that, together with its cage, has a mass of 120 kg when empty. The air in the balloon, which is now carrying two 70 kg people, is heated by propane burners at a location where the atmospheric pressure and temperature are 93 kPa and 12 oC, respectively. Determine the average temperature of the air in the balloon when the balloon first starts rising.
