During the time of the zeppelines, the US had more or less monopoly on Helium, and imposed an embargo on Germany on many things, one being Helium. The Hindenburg was designed for Helium, but had to turn to Hydrogen.
The United States had imposed a military embargo on helium against Germany. However: The gas used for lift was not the main culprit of the Hindenburg accident. The outer skin had been doped in compounds to water proof and reflect light. Unknown at the time was the combination of the two doping compounds was a main ingredient in solid rocket fuels. Helium would not have prevented the Hindenburg accident. Documents later uncovered show that the German government discovered their mistake and quickly covered it up. This action has led many people to the false understanding that the hydrogen lift gas caused the accident.
helium is used to cool superconducting magnets in mri scanners as helium is lighter then air airships use them as gasses
Because helium was not disponible in Germany before the war; USA refused to help Germany with the necessary volume of helium.
The purpose of Helium gas in any airship, including modern airships, is to reduce the overall density and thus provide "lift."
its lighter that air and its everywhere
It wasn't. The US was the biggest producer of helium, and didn't want to sell any to Germany. So they used Hydrogen, which is also light, but very flammable.
They couldn't get any helium because the US had forbidden its allies to sell helium--an important war materiel--to Germany.
The purpose of the helium gas in the GC (gas chromatography) machine is to act as the carrier gas. The helium gas carries the sample through the column, allowing for the separation and analysis of the various components in the sample. Helium is commonly used as the carrier gas due to its inertness and low molecular weight, which facilitates efficient sample transport.
Helium is much less dense than air, meaning it can provide lift. The only gas lighter than helium is hydrogen, which is too dangerous to use for such a purpose because it is extremely flammable. Helium, on the other hand is completely nonflammable. Aside from hydrogen no other gas is anywhere near as light as helium.
Depends on the purpose. But if you combine neon with helium, and obtain a helium-neon laser, you can see that it is much smaller than a xenon laser.
It depends on what you mean. We can breathe helium without any ill effects as long as we get enough oxygen. However, nothing could breathe and use helium as we breathe and use oxygen because helium is inert. Unlike oxygen, which is highly reactive, helium does not participate in chemical reactions, so it could not serve an organism any purpose.
