Im doing a science fair project and need to know how hot air balloons work for my background information if you know and could explain it in simple terms and not confusing words then please do.. if you could, thankyou.

hot air weighs less than cold air, so hot air rises, a balloon full of hot air rises up into the sky, the hotter the air the higher it goes

Hot air rises. Hot air enclosed in a balloon will make the balloon rise. It's as simple as that.

Hot air balloons are based on a very basic scientific principle: warmer air rises in cooler air. Essentially, hot air is lighter than cool air, because it has less mass per unit of volume.

The hot air inside the balloon is less dense than the air around it. Thus, it rises.
Same as a bubble in water. The air inside the bubble is less dense than the water around it. Thus, it rises.

you make a balloon of cloth and then heat the hear until it becomes less dense the the air outside of the balloon which cause you to rise and air currents bring you places

Hot air is lighter than air, hence hot air balloons raise. But gases like Hydrogen and Helium are lighter than hot air and hence are used in Zeppelin's. Helium is preferred over Hydrogen, for it is inert.

hot air is lighter than cold air......this causes it to raise up...if the air is more in quantity and used in a proper manner ...it can take you up
