Helium in balloons is used primarily for buoyancy and does not support human respiration. Oxygen in tanks is used for breathing purposes as it is essential for human survival. The two gases serve different purposes and should not be interchanged.
If I am right in interpreting the question as "Are balloons normally filled with hydrogen and oxygen?", then the answer would be no. Although they can be, as both substances are gases, the majority of balloon are filled with air, a mixture of nitrogen, oxygen, carbon dioxide and other gases. If you mean the balloons that float, they are filled with helium
Helium is used for inflating balloons and dirigible airships.
Helium is used for balloons because it is lighter than air, which allows the balloon to float. This makes it a safe and effective choice for creating floating balloons for parties and events.
Helium is typically used to fill airships and balloons due to its low density, which allows them to float in the air.
Balloons are usually filled with helium gas to make them float. Helium is lighter than air and provides the necessary lift for the balloon to float.
Helium gas is commonly used to fill party balloons because it is lighter than air, making the balloons float.
People generally use helium in balloons because helium is lighter than the air in our atmosphere (mostly carbon dioxide and oxygen), so it floats. As opposed to filling it with oxygen or carbon dioxide, where it would just sink to the ground because it has the same weight as the air it is in.
The density of a helium balloon is less than that of the surrounding air. This is why helium balloons float in the air. Helium is lighter than the nitrogen and oxygen that make up the majority of Earth's atmosphere, so it provides buoyancy for the balloon.
helium is less dense than air. :) so helium will float better than air
Helium balloons float in the air because helium is lighter than the surrounding air. This causes the balloon to be buoyant and rise upwards.
Yes, balloons filled with helium will be buoyant in air
Helium balloons are usually mylar, a metal-coated plastic film while blow-up balloons are usually latex. Helium balloons are usually filled with helium of a decent purity, while blow-up balloons basically have the same gas mixture as the atmosphere around us. A little less oxygen and a little higher humidity if inflated by humans, exactly the same if inflated by a pump. Helium balloons will fly or float in the air, while blow-up balloons won't.
Air is a mixture of gases in which helium is present in atmosphere.It is mostly present in oxygen tanks used by sea divers and in balloons.
because helium is lighter than air,therefore, when letting go of the balloon it will fly up
air and helium
helium
Helium will not burn. Hydrogen burns in air to form H2O (water) Thus in circumstances where a lite gas is required (e.g. in a balloon) it is safer to use Helium. see http://www.unmuseum.org/hindenburg.htm
