Air expands as it is heated, hence, hot air is less dense than cool air. Hence it rises in a surrounding environment of cooler air.
no its filled with hot air from a fire that is lit underneath the balloon.
It is filled with heated air. Since air is mostly nitrogen, a hot air balloon is mostly filled with nitrogen.
A hot air balloon flies because it is filled with hot air. Hot air rises and causes the balloon to lift from the ground.
A typical hot air balloon is filled with the same air we breath.
When a hot air balloon is filled with the hot air the air around the balloon is a lot denser. So by convection the balloon rises and the less dense air is replaced by dense air underneath it.

They are filled with hot air. The hot air raises and take the balloon with it
Relatively hot air balloon are pretty light, and they have a very large balloon which is filled with hot air, which naturally rises, and if you contain enough of it it is enough to lift the balloon.
its air deal with it thank you
Hot air balloons are filled with hot air from a propane burner in the basket. Hot air rises. So provided the cooling air in the balloon is topped up from short blasts from the burner, the balloon will rise off the ground.

Propane gas is used to fuel the burners that heat the air inside the balloon.A hot air balloon is filled with regular air that's heated by a propane burner. This heated air has a lower density than the air outside the ballon, thus allowing the filled balloon to be buoyant.
