being lighter than air, it provides the lifting power
Helium has replace hydrogen in airships
helium, mostly
Yes. Helium isn't flammable, which makes it the safer option.
Airships are usually the shape of a oval. They look like blimps. Airships are usually filled with helium to keep them afloat.
Helium is typically used to fill airships and balloons due to its low density, which allows them to float in the air.
Hydrogen (explosive), Helium (non-explosive).
Hydrogen and helium are two elements that are kinda-sorta interchangeable in airships.
The gas that helium replaced was Hydrogen
Helium is inert. Will not burn like hydrogen does so well.
helium is used to cool superconducting magnets in mri scanners as helium is lighter then air airships use them as gasses
Helium is a lighter gas than oxygen, ever seen balloons filled with helium? They rise upwards with heat due to a lesser amount of particles. If we used oxygen, the airships wouldn't get off the ground!
Hydrogen and helium gases are commonly used in airships for lift. Helium is safer than hydrogen due to its non-flammable nature, although it is less buoyant.
