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.
'Helium' because it is also an INERT (Noble) gas. Hydrogen could be used to make the balloon float/rise, but hydrogen is a flammable gas. On explosion you will have a flash of flame.
Hydrogen is the lightess, but most common element in the galaxy. It can be used to make balloons rise, be burned to give off heat, or burned to give engine thrust.
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!
they don't float ONLY with helium. They float with any gas that is less dense than air, for instance hydrogen.
Hydrogen is a gas at room temperature and standard pressure.
helium, hydrogen, nitrous oxide, oxygen
Hydrogen is too flammable
Fill two balloons. One with hydrogen gas and the other with helium gas. Allow them to float on a piece of string. Taking a lighted/burning taper/splinter. , and burst the two balloons with the burning splinter. The helium filled balloon will just 'pop' and fall to the ground. The hydrogen filled balloon will 'pop with a flash of flame' So helium ; NO Flame Hydrogen ; A FLASH of FLAME.
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 is used in blimps and balloons. It is the second lightest element to hydrogen, which is not used because it is highly flammable.

Hydrogen
They are filled by Hydrogen gas.
Hydrogen is highly flammable and can easily explode. Helium is a more stable gas.
Two of the gases that are used to fly balloons are Hydrogen and Helium. Helium is the preferred gas because Hydrogen is very explosive. The Hindenburg disaster was caused by the ignition of the Hydrogen gas that filled it.
Helium is an inert gas."They fill Helium in the balloons", father explains his child.
