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.

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 should a hot-air balloonist do to get higher?
Through the use of a burner heat up the gas inside the balloon.
Why do you use hot air for hot air balloon instead of cool air?
Hot air rises.
Why the hot air balloon needs hot air to make it rise?
Hot air balloons use hot air because hot air rises above cold air. The air inside the balloon is heated above the temperature of the air outside the balloon. The warmer air trapped inside the balloon then causes the balloon to float above the outside colder air.
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 energy does hot air balloon use?
Heat energy
How is a hot balloon lifted into the air?
to make a hot air balloon rise you use hot air
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 use of air in air balloon?
with out the hot air the balloon would not rise

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

What is the type of gas they use in hot air balloons during 1999?
Hot air balloon pilots use propane to heat their balloons. It's inexpensive, very easy to obtain, and works.
