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.
Helium gas is commonly used to fill party balloons because it is lighter than air, making the balloons float.
If you want the balloons to float, you would probably use helium.
element
Helium is commonly used to fill balloons. It is non-flammable and lighter than air, allowing balloons to float.
Helium is a colorless, odorless, and tasteless inert gas that is used in various applications such as in balloons for parties and in cryogenics for cooling superconducting magnets.

They Do Not use Hydrogen gas to fill up balloons. People use Helium gas to fill up balloons (ordinary party balloons, and big working balloons such as the one used by Goodyear). Helium is Not Flammable. Hydrogen is Flammable and has as tendency to burst into Flame, similar to the German Blimp/Dirigible Hindenburg. Since the US Navy lost Two Helium Blimps in Bad weather; The Akron and the Shenandoah (with a great loss of lives), the US Navy almost never uses Blimps anymore.
They're filled with Helium.
One example of a gas would be helium. Helium is used to fill up balloons and make them float.
Yes, it is possible to fill balloons with argon gas. Argon is commonly used in balloons that require a more stable and non-flammable filling gas, such as for special events and experiments. However, argon is more expensive than other gases like helium, so it is not as commonly used for everyday balloons.

Helium is the safest gas to fill in balloons, as it is light and noncombustable.
if its possible then the reason could be the expansion of high pressured helium from tank to balloon is large.
