Helium is lighter than air, hence it will rise up in air, making things fly.
It is a super light gas .... trust me
helium is less dense than air. :) so helium will float better than air
because helium does not mix with other elements
Helium is used in balloons because it is much less dense than air, allowing the balloons to float and is completely nontoxic and nonflammable unlike hydrogen, which is otherwise a superior lifting gas.
Balloons filled with helium float because helium is lighter than the surrounding air, creating a lifting force. This is known as buoyancy. Regular air-filled balloons are denser than the surrounding air and do not float.
Helium is safer than hydrogen in hot air balloons because it is non-flammable. Hydrogen can ignite easily, posing a greater risk of fire. Additionally, helium is more stable and its lifting capacity is sufficient for use in hot air balloons.
Hydrogen was one of the earliest gases to be used for inflatable flying balloons, but following the Hindenberg disaster helium is now used, as it is chemically inert.
10000000 helium balloons
Helium is used in balloons instead of hydrogen because it is non-flammable. Hydrogen is flammable and can be dangerous, while helium is inert and poses less of a fire risk. Additionally, helium is less dense than air, providing better lift for balloons.
Helium is the lightest non-flammable gas. It is colorless, odorless, and tasteless, making it safe for a variety of applications such as lifting balloons and as a coolant in various industries.
Balloons are not called helium; they can be filled with helium because this gas is not flammable and has a very low density.
Hydrogen gas makes the ballon lighter than air therefore it drifts upwards
