22.4 liter of Helium will weight 4.0026 g
At standard pressure and temperature: approx. o,9 g.
Not nearly as much as you'd suspect; the available volume inside the tires isn't very large, and even pumping in pure helium wouldn't so much as negate the weight of each tire.
Soccer balls do not contain helium. if they did, they would float like a balloon! Actually, that's not true. A soccer ball would NOT float like a balloon--they weigh too much. It would, however, increase the distance ever so slightly over that of a regular air filled soccer ball. Eventually over time, the helium would dissipate, much like a helium balloon that slowly falls to the ground.
On a 1997 Yamaha 600 the factory tire pressure is 36 psi. Be sure when fill the tire to fill for the recommended pressure as to much will lead to damage and to little to loss of performance.
Usually not. Apart from Helium being a very light gas its is also a very small molecule, it is harder to contain than other gasses made up from bigger molecules.(helium is routinely used when checking for leaks in hermetically sealed systems. Partly due to traces of Helium being easy to detect, partly because if helium can't get out, then nothing else will.) A Helium filled tire would lose pressure much faster than a tire filled with ordinary air. On top of that Helium is a bit expensive, and has to be bought in bottles. Not much point in using something that is more expensive and does a poorer job than something that's free only to save a few grams of weight.
The amount of helium in a tank depends on how big the tank is (volume), the pressure of the helium and its temperature. It is calculated from the ideal gas equation with allowance for compressibility.
That depends on the pressure inside the container. You can cram 1 lb of helium into any container, as small as you want. On the other hand, it'll always spread out and fill any container you put it in, no matter how large. So if you want to know how much volume a sample of helium will fill, you have to specify the pressure. By the way ... the temperature also affects the pressure of a gas, so you have to specify the temperature too.
If James is holding that much helium, he would be talking funny
A sphere with 3-ft diameter has about 0.4 cubic metre of volume.
Check door jambs or fuel fill door - should be a label telling you how much
Depends on car, type of tire and size of tire.
