  3. Hot air ballons rise because of the lower density of the gas inside, compared to outside, the balloon. The fact that the air is hot is what reduces the density, but cold helium or hydrogen would work even better.

    The balloon is pushed upward by the greater outside pressure on the bottom compared to the top of the balloon. Pressure is due to molecular collisions wth the wall. There are more molecules colliding with the bottom than the top. There is a similar effect inside the balloon, pushing the balloon down, but because the density inside is lower, the net force is up.

  5. so is it something like this

    The flight path of a Hot Air Balloon is ultimately controlled by thermal energy regulation. This regulation of the heat gives the pilot a precise control of the altitude of the balloon, which in turn provides for any lateral control that might be possible, considering the atmospheric conditions. There are many parameters that affect this thermal energy regulation. Heat is added by the burner until the (ambient envelope) temperature differential is in excess of 100 degrees Fahrenheit, but the burner is not the only source that adds to (or subtracts from) this temperature differential. The radiative and convective heat transfer processes that contribute to the problem of thermal energy regulation are very important, and can significantly affect balloon performance.
