Hydrogen is not used to inflate hot air balloons. Just regular air is used which is then heated to make the balloon more buoyant as hot air weighs less than cold air. Hence the name hot air balloons.
because it helps it fly in air
Hydrogen gas was used in air balloons because it is much less dense than air and therefore rises, taking the balloon with it. it is unfortunately also very explosive so not used often anymore.

Lighter-than-air balloons are aircraft that achieve buoyancy and rise in the atmosphere by being filled with gases that are less dense than the surrounding air, such as helium or hot air. These balloons rely on the principle of buoyancy, where the lighter gas displaces a greater weight of air, allowing them to float. Common types include hot air balloons, which use heated air, and gas balloons, which are filled with helium or hydrogen. They are often used for recreational purposes, scientific research, and advertising.
For small balloons like individuals often have for recreational use, hot air is much easier to control than either hydrogen or helium.For the occasional blimp, or long distance balloon trip, Helium, while somewhat heavier than Hydrogen, has proven to be far safer.The Hindenburg has proven the inherent dangers of using Hydrogen Gas in blimps. While, in theory, pure hydrogen is not explosive without the presence of oxygen, any rupture in the thin material separating hydrogen from the air atmosphere can prove to be deadly.
Helium, hydrogen, and carbon dioxide can also be used to inflate balloons, depending on the desired effect. These gases are often used in balloons for parties, decorations, and scientific experiments.
Helium is used to inflate balloons because it is lighter than air and that makes the balloon float.
Helium is a gas used to inflate lighter than air balloons.
Any gas will inflate the balloon. It simply needs to be introduced into the balloon at a pressure greater than that of the surrounding atmosphere (plus some additional allowance for the pressure required, if any, to stretch the balloon material).
'Hot air' balloons don't use hydrogen. They use hot air. Balloons that use hydrogen are not referred to as 'hot air' balloons. The only balloons that can accurately be referred to as 'hot air' balloons are the members of the balloon population that derive their lift/buoyancy from the presence of hot air. Of course, if a balloon used no hot air, then it could freely be referred to as a 'hydrogen' balloon, a 'helium' balloon, a 'water' balloon, etc., depending in congruent harmony with the nature of whatever substance had been chosen with which to inflate it it in order to maintain its fulsome shape.

To inflate means to fill something with air or gas in order to make it expand or become larger and more firm. This process is commonly used in activities like inflating balloons, tires, or air mattresses.
Helium is the most used gas for balloons; sometimes hot air and rarely hydrogen.
You can inflate objects and make them bigger by adding air to the object. Balloons and tires are objects that require air in order to inflate and make them bigger.
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.
You can inflate a balloon without air by using a different gas, such as helium, which is often used for party balloons. Alternatively, you can use a manual or electric pump to inflate the balloon with a liquid, such as water, which will evaporate and create gas inside the balloon.
Helium (Hydrogen could also be used but this is flamable). Not some balloons are also kept aloft using hot air.
