Hydrogen gas makes the ballon lighter than air therefore it drifts upwards
Helium OR Hydrogen. (or hot air).
The most common gas is now helium.
either for balloons, or whip it's.
Helium is a gas used to inflate lighter than air balloons.
helium, hydrogen, nitrous oxide, oxygen
If you want the balloons to float, you would probably use helium.
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.
It is a super light gas .... trust me
Helium is used in balloons because it is much less dense than air, allowing the balloons to float and is completely nontoxic and nonflammable unlike hydrogen, which is otherwise a superior lifting gas.

Hot air is used for hot air balloons.

to keep the balloon floating
helium
hydrogen is used for carsHydrogen is also used for air crafts and to power buildingsAnswer # 2History tells us that Hydrogen gas was used for lifting in balloons, today they are using Nickel hydrogen in batteries.Please see related link below!
