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.
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.
Hot air balloons typically use propane gas as fuel to heat the air inside the balloon envelope, which makes the balloon rise and float.
Heat is used in a hot air balloon to create buoyancy. When air inside the balloon is heated, it expands and becomes less dense than the cooler air outside, allowing the balloon to rise. By controlling the temperature of the air inside the envelope, the pilot can ascend or descend as needed. This principle of buoyancy is fundamental to the operation of hot air balloons.
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...
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.
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.
A hot air balloon is normally powered with propane. Other than that, it is just ordinary air used inside the balloon.

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.
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.
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.

Yes on both counts. But hot air balloons need considerably more help - they use propane burners to heat the air inside the balloon.
with out the hot air the balloon would not rise
