We consider a hot-air balloon of mass 231 kg (basket and envelope). The spherical envelope of the balloon has a diameter of 15 m when fully inflated. To what temperature (in °C) must the enclosed air be heated for the balloon to carry five standard men? Assume the surrounding air is at 20°C and is treated as an ideal gas. Use 29 g/mol for the molar mass of air. (Assume the mass of each standard man is 70 kg.)

A hot air balloon starts to take off when the temperature inside the balloon is 111 °C higher than the outside air. The pressure is the same inside and outside the balloon and there is a total of 2.50× 105 moles of air in the balloon. Assuming that the air density outside of the balloon is 1.20 kg/m3, what is the total mass of the balloon and its load? The answer is 2.73 × 103 kg. I am not sure...

You are helping to design a new hot air balloon for an upcoming regatta. Assuming that the temperature to which the air inside the balloon can be safely heated is 85 ˚C, what is the minimum volume require for the balloon if it is to lift a total weight (balloon plus passengers) for 250 kg. Take the outside air temperature to be 15 ˚C, the air pressure to be 1.00 bar, and make a reasonable assumption as to the composition...
