Best Answer

helium can lift about 0.067 pounds per cubic foot because that is the difference between its weight and it's upward force

so

120 / 0.067 = 1791.044776119403 cubic feet of helium assuming that it is contained by baloons

without baloons, the helium will just simply get trapped in the atmosphere.

What properties make helium useful?

While it is not a "Noble Gas" it is much lighter than air. It is not lighter than Hydrogen, but it does not ignite as easily.

If you put helium into a tank will the tank get lighter?

yes it will, but not by much


How much faster does helium diffuse than oxygen?

Not much faster, but it does diffuse faster than helium because it is lighter.


What nuclear process coverts helium and hydrogen gases from lighter to heavier elements?

The process is called fusion; hydrogen nuclei are fused together to make helium. At much higher temperatures and pressures, the helium can fuse into carbon and nitrogen and oxygen.


Why does helium rise while carbon dioxide sink?

This is because helium is much lighter than our atmosphere of oxygen, nitrogen and other gases so it floats.


Why is helium used in modern day airships even though hyrdogen is much lighter and could carry greater loads?

Because Helium is inflammable and the safer choice.


Will a basketball blow up if you put helium in it?

That all depends how much helium you put in it. A basketball should be able to take the same amount of pressure, whether it's pressure from air or helium. So, if you inflate it only to the recommended pressure, it should be a problem. The same amount of pressure of helium will be less mass, so in the end the basketball will be lighter, as you would probably expect, by a very small amount.


Is helium lighter than air?

Yes, a mole of hydrogen weighs 1 g, a mole of helium weighs 4 g. Still lighter than air, as a mole of air weighs about 30 g.


is helium used in air balloons?

It can be, but usually not. Helium is a bit expensive, and it'd cost too much for most balloonists to use it. It's cheaper to use a hot air balloon. helium is lighter than air. hence balloons filled will helium will float in air.


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.


Why do balloon contains helium?

Helium is much less dense than air, which allows balloons to float. It is also chemically inert, which means hazards associated with it are minimal. Hydrogen gas is lighter and easier to obtain, which would make it seem ideal, but it is also highly flammable, which makes it dangerous.
