What is added to balloons and hot air balloons?
Balloons can be filled with air (don't float), or with hydrogen or helium (float because the gas is less dense). Hot air balloons use burners to heat the air so that it becomes slightly less dense than the cooler air around it, providing some lift.
What fuel do hot air balloons use?
Fire and, well, hot air.
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 2 things that use hot air to rise?
hot-air balloons and birds in flight.
Which gas is used to fill balloons?
Helium is normally used in balloons that float. Helium is the second lightest gas. Hydrogen is lighter, but it is also flammable and thus dangerous.When normal air is used to fill a balloon, the balloon will not be buoyant.If you fill a balloon with air from your lungs, there is a bit more water vapor and a bit more carbon dioxide and a bit less oxygen in the air inside the balloon, but that has a small impact on the buoyancy.The larger balloons that carry people are called hot air balloons because they are filled with hot air. They are buoyant because the hot air is fractionally lighter than normal air but there is a lot of it.Weather balloons and party balloons both use helium gas.As long as the gas plus the balloon is lighter than the air it displaces, the balloon will float in the air.Helium is normally used in balloons that float.

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.

How do hot air balloons use air to fly?
Hot air balloons use the fact that hot air rises as a way to make balloons fly. When the air inside the balloon is heated, it rises, and this creates lift which is used to make the balloon fly.
What fuel do hot air balloons use?
Fire and, well, hot air.
Why do hot air balloons use hydrogen?
'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.
Which gas is used to fill the balloons?
Hydrogen, until the Hindenburg,then everyone realized that "Hey, Hydrogen isn't that safe to use!"Hot air balloons, you mean?? Just air that is hot.Actual hand balloons and such? Helium or again, just air. Helium floats better because it is lighter than the surrounding air around it. Helium and air are still used in both.
What gas is used in hot airships?
hot airships don't really exist. you get hot air balloons, but they're only marginally steerable. If you were to find a hot air ship, well, then lift would be provided by the hot air. The gas they'd use to create that hot air would be propane.

How were hot air balloons used by the military?
The first use of hot air balloons was in the American Civil War for surveillance of troop movements.
Do they use fire with hot air balloons?
Yes
Why do hot-air balloons use fire?
Yes
