Hydrogen was once used to fill airships. Quite dangerous due to how flammable it is.
gas is still used in airships to provide lift.
Hydrogen was the gas that was once used to filled airships. It is extremely plentiful and easy to produce. However, it is also extremely flammable and caused a few accidents. Helium is now used.
because hydrogen used to be in those airships and since hydrogen is flammable it was very dangerous
hydrogen is VERY flammable, which makes it an unpleasant choice.
Helium has replace hydrogen in airships
Airships do use gas, to provide lift.
Today's blimps are not filled with flammable hydrogen gas like Hindenburg was, but normally the non-flammable helium.
Hydrogen isn't used for airships because it is highly flammable. It was one of the causes of the Hindenburg's burning.
coz it is flammable....
hydrogen or helium.
the gas that helps airships is i hate you wikianswers.com
A flammable gas once used to fill blimps
Airships were often used to carry freight and passengers. But became unpopular after the advent of jets and other types of aircraft because they are slow. Initially they used fuel which made them highly flammable when accidents occured.
The only answer that comes to mind is "Airships". Hydrogen, the lightest element, was used in airships, where excess weight was undesirable. However, accidents like the Hindenburg disaster showed that Hydrogen gas was too dangerous(it is extremely flammable) to be used. Since then, Helium has been used instead. Helium is also a very light element, and is completely safe, as it is inert.
Yes. Helium isn't flammable, which makes it the safer option.
Due to the fact that its extremely flammable
Hydrogen was used for balloons and airships(zeplins) because it is the lightest gas, but highly flammable, so now we use helium because it is very safe. Hope this helped xxx
In their early history, buoyant airships (zepellins, blimps) were filled with hydrogen, a highly flammable gas. Since the Hindenburg disaster, hydrogen has been supplanted by helium, a much more expensive material, but one that is inert and hence much safer.
Because helium is an non flammable gas, which proved a much safer alternative to the hydrogen airship following the explosion of the LZ129 Hindenburg on May 6th 1937.
The gas was Hydrogen.
Flammable gas will burn. Toxic gas is poisonous. A gas can be toxic, but not flammable, flammable but not toxic, both, or neither.
Hydrogen gas is flammable. Hydrogen has been used in the past as it has much greater lift capacity than Helium but H2 flamability was made all too apparent when the Hindenburg burned in New Jersy in 1937 killing 35 of the 97 on board.
