What is a very light gas found in some balloons?
Helium is used in blimps and balloons. It is the second lightest element to hydrogen, which is not used because it is highly flammable.
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
Which gas is used to fill the balloons?
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.
Is oxygen lighter than helium?
no. If it was, we would have oxygen balloons instead of helium balloons.
Why do modern spacecraft use helium instead of hydrogen?
Helium is much safer, so it is often used in balloons and blimps, not spacecraft.Hydrogen is still used as a fuel. Helium will not burn.
Why is density of hydrogen lower than air and can be used to fill balloons why is helium used instead oh hydogen?
Because helium is lighter

Why helium is better than hydrogen for balloons?
because helium does not mix with other elements
Why is Helium gas used in gas balloons instead of hydrogen gas?
Hydrogen is highly flammable and can easily explode. Helium is a more stable gas.
Why are helium used instead of hydrogen for balloons?
Helium is an inert light gas where as hydrogen is an explosive gas andto dangerous to use.Hope this answers your question.
Which other gas instead of hydrogen can be used for air balloons?
Helium - it's less reactive.
What are the gases used to fly balloons?
Two of the gases that are used to fly balloons are Hydrogen and Helium. Helium is the preferred gas because Hydrogen is very explosive. The Hindenburg disaster was caused by the ignition of the Hydrogen gas that filled it.

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.
Why is hot air better than helium in hot air balloons?
Hot air balloons use hot air. They have a burner to heat the air. Hydrogen balloons were too dangerous because hydrogen is highly flammable, even static electricity could cause an explosion. Helium is safer because helium is not flammable.
