Because hot air rises. And I assume because burning fuel to create the hot air is easier, perhaps a lot lighter as well, and definitely cheaper than constantly buying helium. Although blimps used that method.

How do you make a hot air balloon without fire?

One way to make a hot air balloon without fire is to use a heat source other than flame, such as a heat gun or hair dryer, to fill the balloon with hot air. The hot air will cause the balloon to rise and float. Make sure to use caution and follow proper safety measures when using alternative heat sources.


What fuel does hot air bloons use?

Hot air balloons typically use propane gas as fuel to heat the air inside the balloon envelope, which makes the balloon rise and float.


Why does a hot air balloon need a burner to work?

To keep it hot you. The REASON they use a 'Burner' in a Hot Air Balloon is to 'heat the Air, to 'fill' the Balloon, so it will 'rise'... The only other way to get the air Hot enough to fill the Balloon, would be to make the 'Basket' MUCH, MUCH Larger, and fill it with Liberals, and just let them talk. BUT, I don't think the Balloon would ever get off the ground, because, the BULLCRAP would counteract the Hot Air, and they would cancel each other out...


What kind of fuel is used for the hot air balloon?

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.


Where does the hot air balloon energy come from?

Most hot-air balloons use propane (a liquified petroleum gas) as fuel for burners which heat the air in the balloon. The heated air has lower density than the air outside the balloon, which gives it buoyancy and generates lift.

What energy does hot air balloon use?

Hot air balloons use the energy generated by heating the air inside the balloon with a propane burner. This heat creates a temperature differential that causes the balloon to rise. As the air inside the balloon cools, it descends, allowing the pilot to control the altitude of the balloon.


What type of gas is used in a hot air balloon?

A hot air balloon is normally powered with propane. Other than that, it is just ordinary air used inside the balloon.

What fuel do hot air balloons use?

Hot air balloons use propane gas as fuel to heat the air inside the envelope, which causes the balloon to rise. The propane burner provides the necessary heat to keep the air inside the balloon hotter than the air outside.


What element is used in a hot air balloon?

Hot air balloons typically use propane gas as a fuel source to heat the air inside the balloon envelope, causing it to rise and lift the balloon off the ground.


Which gas do you use for hot air balloons?

Hot air balloons typically use propane gas as a fuel source for the burner that heats the air inside the balloon envelope. The propane is burned to heat the air, which causes the balloon to rise.


What is the use of air in air balloon?

with out the hot air the balloon would not rise


Does the sun heat air and hot air rise?

Yes on both counts. But hot air balloons need considerably more help - they use propane burners to heat the air inside the balloon.

What is the difference between a helium balloon and a hot-air balloon?

A helium balloon does not need energy to rise in the air. A hot air balloon needs fuel to rise in air. That is it needs heat energy to rise in air.i love Pizza squares i hope they put helium in then one dayHelium relies on the fact that helium is lighter than air. Hot air balloons rely on the fact that hot air has less volume than cold air and is lighter than the air around it. hot air balloons use hot air to cause the balloon to lift as helium balloons use a special gas to cause lift
