'Hot air' balloons don't use hydrogen. They use hot air. Balloons that use hydrogen are not referred to as 'hot air' balloons. The only balloons that can accurately be referred to as 'hot air' balloons are the members of the balloon population that derive their lift/buoyancy from the presence of hot air. Of course, if a balloon used no hot air, then it could freely be referred to as a 'hydrogen' balloon, a 'helium' balloon, a 'water' balloon, etc., depending in congruent harmony with the nature of whatever substance had been chosen with which to inflate it it in order to maintain its fulsome shape.
not at all
A chemical reaction in a hot air balloon can be when the propane is heated up. That is a chemical reaction because something has heated up.
A chemical reaction takes place every time a hot air balloon flies. Specifically, a combustion reaction occurs when the fire from the propane tank heats the air inside the balloon.
air
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 hot air balloon is normally powered with propane. Other than that, it is just ordinary air used inside the 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
Hot air is common.
No Gas Just hot air which is why it is called a hot air balloon. If you were wondering hot air is lighter than cold air which makes it rise so when it is trapped inside the balloon the whole thing will rise.
The gas is hot air.
A hot air balloon can be used for weddings, commercial, and just plain leisure. It can also be used to observe an enemy or drop bombs on them.
A hot air balloon flies because it is filled with hot air. Hot air rises and causes the balloon to lift from the ground.
Because the fire or heating device heats the air in the top section ( the actual balloon ) and hot air rises... so the hot air trapped in the balloon makes the balloon rise :)
to make a hot air balloon rise you use hot air
