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.
Hydrogen was used in air balloons at older times. but at present we use helium gas in air balloons . helium is an inert gas.
There are two gases that are lighter than air, most commonly Helium is used in balloons because the other gas, Hydrogen is explosive.
Examples: helium, hot air.
Hydrogen.
hileum
helium, hydrogen, nitrous oxide, oxygen
If you want the balloons to float, you would probably use helium.
element
Helium is an inert gas."They fill Helium in the balloons", father explains his child.
Yes, helium is an example of a gas. It is a colorless and odorless gas that is lighter than air. It is commonly used to fill balloons and in various scientific and industrial applications.

They're filled with Helium.
element
One example of a gas would be helium. Helium is used to fill up balloons and make them float.
Helium is an inert gas."They fill Helium in the balloons", father explains his child.
Helium is the safest gas to fill in balloons, as it is light and noncombustable.
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.
