Is balloons filled with hydrogen and oxygen?
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
What noble gas is used in party balloons and weather balloons because it is lighter than air?
helium
Helium is used in balloons because?
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.
What is the gas that you use in balloons?
The gas commonly used in balloons is helium. It is lighter than air, which causes the balloon to float when it is filled with helium.
Is air and oxygen are the same gas?
air has oxygen in it but also other gases, e.g. helium nitrogen.
What chemicals do balloons contain?
helium or oxygen depending on what you put in them
Why helium is used on a large scale in balloons?
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.
What form is helium?
hot air balloons and balloons
Why do helium balloons float better than just air balloons?
helium is less dense than air. :) so helium will float better than air
Why is helium used to fill balloons instead of oxygen or hydrogen?
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
Is helium suitable for blowing up balloons?
Yes, balloons filled with helium will be buoyant in air
Why do balloons fly with helium and not with normal human oxygen?
because helium is lighter than air,therefore, when letting go of the balloon it will fly up
Where you can find helium from your surrounding?
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.
How is the helium in the tank different from the helium in the balloon?
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.
What gases are in balloons?
air and helium
What air is inside balloons?
helium
Why do helium-filled balloons float up in the air?
Helium is lighter than air.
