The body of a hot air balloon has the volume V = 4300 m3. The mass of the balloon body together with the person is m = 1000 kg. (The air can be treated as an ideal gas) Consider that the surrounding air has a temperature of T=15 C The air pressure decreases with the height, given by: p(h) = po e hk where h 8400m Exercise: 1. Calculate the air density at 4200 m 2. Which temperature does the air inside the balloon needs to be, so the balloon floats
