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 is a colorless gas that is commonly used to fill balloons to make them float. It is lighter than air and non-flammable, making it safe for use in balloons.
Hydrogen is used in weather balloons because it is a very lightweight gas that provides the necessary buoyancy to lift the balloon and its payload to high altitudes. It is also readily available and less expensive compared to other gases like helium.
Jacques Alexandre Charles first attempted to use hydrogen as a replacement for hot air in hot air balloons in 1783. This led to the first manned flight using hydrogen gas in December of the same year.
Hydrogen is used in filling meteorological balloons because it is a light and non-reactive gas that can quickly lift the balloon to high altitudes. Its buoyancy allows the balloon to rise rapidly and reach the desired height for collecting atmospheric data. Although hydrogen is flammable, the small amount used in meteorological balloons is considered safe.
It is a matter of mass, weight, and density. A balloon filled with normal air will not rise. Air will rise in water, because it is less dense (bubbles). Helium on the other hand is lighter than air, so it too will rise when 'submerged' in it. The actual process is that the heavier air surrounding a helium-filled balloon will "displace it" and force it upward. Hydrogen is also less dense than air, but it is flammable. Helium is not flammable, has no smell or taste, and is not poisonous. So because it is the second lightest element, and the second most plentiful in the world (found in natural gas), it's a natural fit. ---- However, consider that while it may seem fun to have balloons that go up on a string, if they escape, then eventually they pop and it is likely that the burst rubber will fall into the sea. In the sea they are mistaken for food by turtles and escaped balloons cause much harm. Also being unreactive as an element and very light, most of the helium on earth has gone to the top of the atmosphere and escaped into space. The only helium we have is found as a byproduct of radioactive decay within the Earth. The element has very important uses in industry and science and wasting it on balloons is not a sensible thing to do. There is only a finite amount of helium available to us at any given time.

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 gas is highly flammable and can easily ignite, posing a safety risk in balloons. Helium gas, on the other hand, is non-flammable and is therefore the preferred choice for inflating balloons to ensure safety.
hydrogen gas
Helium is used in blimps and balloons. It is the second lightest element to hydrogen, which is not used because it is highly flammable.
No, Hydrogen is a gas. The verb "fly" can not be applied to a gas.
hydrogen, helium, hot air
Hydrogen
They are filled by Hydrogen gas.
Any Gas with a lower density than 1.2kg/m^3 will make a balloon rise. However I think you are talking about helium. Gases that are lighter than air like Hydrogen etc Helium Is the lighter than air gas that is used to fill party balloon's it is an inert gas, that is it doesn't burn unlike Hydrogen which is the gas that was used in the Hindenburg air ship.
Hydrogen is highly flammable and can easily explode. Helium is a more stable gas.
