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.

Is there helium in airships?
Yes. Helium isn't flammable, which makes it the safer option.
Why does an airship float in air?
An airship uses helium which weighs less than air, and it cancels out the weight of the airship. Hydrogen weighs even less than helium, but it is combustible, so helium is preferred for use in airships.
What gas do you use in airships today?
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.
What are two differences between the good blimps of today and the airships Hindenburg?
Today's blimps are not filled with flammable hydrogen gas like Hindenburg was, but normally the non-flammable helium.
What is the advantages and disadvantages of foreign trade multiplier?
advantages of foreign trade multiplier
What gases are in an airship?
Helium has replace hydrogen in airships
What are airships filled with now?
helium, mostly
Is there helium in airships?
Yes. Helium isn't flammable, which makes it the safer option.
What is one use of helium?
Helium is used for inflating balloons and dirigible airships.
What shape are most airships?
Airships are usually the shape of a oval. They look like blimps. Airships are usually filled with helium to keep them afloat.
What is a light element used for lifting airships?
Hydrogen (explosive), Helium (non-explosive).
Which element is also used in airships?
Hydrogen and helium are two elements that are kinda-sorta interchangeable in airships.
What element is used to fill airships and balloons?
Helium
Which floatation gas has been replaced by safer helium in airships?
The gas that helium replaced was Hydrogen
Why is helium safer then hydrogen for use in airships?
Helium is inert. Will not burn like hydrogen does so well.
What is the main purpose of helium?
helium is used to cool superconducting magnets in mri scanners as helium is lighter then air airships use them as gasses
Why is helium used in airships rather than oxygen?
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!
