The force that lifts a hot air balloon is called buoyancy.
Bouyancy, pressure, and gravity.
upthrust and gravity
the higher you go the lighter the air is.
A hot air balloon is normally powered with propane. Other than that, it is just ordinary air used inside the balloon.

Hydrogen is used. Sorry. Just regular air is used in a hot air balloon, it is heated which makes it lighter and less dense and therefore provide lift. Hence the name hot air balloon. Hydrogen is used in a gas balloon.

A typical hot air balloon is filled with the same air we breath.
A hot air balloon can stay in the air because the hot air is less dense than cool air. The hot air that is blown into the balloon causes it to rise and a burner is used to heat the air inside of the balloon to keep it floating.
no, hot air air is used
Buoyancy, air resistance and gravity. Hope this helps!! :)
Hot air is common.
hot air rising (less dense air), gravity. aero dynamics dont do much
