What flammable gas used to be used in airships?
Hydrogen used to be used in airships.
What did hydrogen used to be used for?
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.
Why is hydrogen not used to fill airships any more?
In 1931, a large passenger dirigible lifted with hydrogen burst into flames while landing in Lakehurst, NJ. Since then, hydrogen has been considered too dangerous to use in airships under normal conditions. because hydrogen is a very flammable gas and can catch fire easily on an airship. an example of this is the Hindenburg in 1937
Why are helium and hydrogen used in airships?
Hydrogen and helium are used in airships because there are less dense than air. That means that if we fill a big, lighweight bag with hydrogen or helium, the bag will be lighter than air and will provide lift. It will float off the ground. Hydrogen is cheaper to come by, but it is so terribly flammable that it is too dangerous to be used in airships any more. The Hindenburg was filled hydrogen, and…
Why is hydrogen not used to fill balloons?
Hydrogen is lighter than air, so any balloon filled with H2 gas will float. The problem is that hydrogen gas reacts extremely well with oxygen, meaning that its VERY flammable. The original airships of the 19th century and early twentieth used to be filled with hydrogen gas, and were known as Zeppelins. This mode of flight by airship was generally abandoned after the disaster of the zeppelin Hindenburg in Trenton New Jersey in 1919, when…
Compare and contrast ethane ethene and ethyne?
Ethane - A colorless odorless alkane gas used as fuel. Ethene - A flammable colorless gaseous alkene; obtained from petroleum and natural gas and used in manufacturing many other chemicals; sometimes used as an anesthetic. Ethyne - A colorless flammable gas used chiefly in welding and in organic synthesis.
What are The advantages and disadvantages of helium in airships?
First of all, there isn't much choice. To get the airship to lift, one has to use a gas that's lighter than air. Only two do that well enough to be useful, hydrogen and helium. Hydrogen is lighter and cheaper, but horribly flammable. Helium is more expensive, provide less lift, but is entirely non flammable.
