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.
i think is 44,300 liters cause it takes 443 litter to pick up one pound i think is 44,300 liters cause it takes 443 litter to pick up one pound
Carbon dioxide will keep a balloon inflated longer than helium will, because its molecules are much larger and therefore less able to escape through the material of which the balloon is made.On the other hand, helium is much lighter so will give a balloon greater lift while it lasts.
The density of helium is approx. 0,9 g/L.
Approximately 15 cubic feet of Helium.
A pingpong ball. There much lighter like if i throw them at my head with my shotgun it will not hurt much.
one pound
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.
How much does the element helium cost per pound? hmm. idk go ask someone else
yes it will, but not by much
Not much faster, but it does diffuse faster than helium because it is lighter.
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.
This is because helium is much lighter than our atmosphere of oxygen, nitrogen and other gases so it floats.
Because Helium is inflammable and the safer choice.
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.
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.
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.
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.
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.
