Why is helium used in a zeppelin?
Helium is much less dense than air, meaning it can provide lift. The only gas lighter than helium is hydrogen, which is too dangerous to use for such a purpose because it is extremely flammable. Helium, on the other hand is completely nonflammable. Aside from hydrogen no other gas is anywhere near as light as helium.
Which has the least number of atoms 5g of hydrogen or 10g of helium?
10g of helium has fewer atoms. This is because the atomic mass of helium is much higher than that of hydrogen, so the same mass of helium contains fewer atoms than the same mass of hydrogen.
What are the two main elements of the sun?
Hydrogen and Helium. Also comprised of a core of much heavier elements, all the elements in the universe heavier than hydrogen probably came from supernovae.
What is the second lightest gas?
The second lightest gas is helium. The lightest gas is hydrogen which is also the lightest element. They are very close on the Periodic Table.
Helium is used in balloons because?
Helium is used in balloons because it is much less dense than air, allowing the balloons to float and is completely nontoxic and nonflammable unlike hydrogen, which is otherwise a superior lifting gas.
Is helium lighter than air?
Yes, helium is lighter than air. Helium is a lighter-than-air gas that has a lower density compared to the gases that make up our atmosphere, such as nitrogen and oxygen. This is why helium-filled balloons float in the air.
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.
Why does sound travel faster in helium than in air?
Sound travels faster in helium than in air because helium is much lighter than air, which causes sound waves to travel more easily and quickly through it. The lower density of helium allows sound waves to move faster and with less resistance compared to air.
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.
How much hydrogen helium is on Saturn?
About 96% is hydrogen, about 3% helium.
Is Saturn lighter or heavier than water?
Saturn is much lighter than water. It is a gas giant made primarily of hydrogen and helium, with a density lower than that of water.
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 is helium used in a zeppelin?
Helium is much less dense than air, meaning it can provide lift. The only gas lighter than helium is hydrogen, which is too dangerous to use for such a purpose because it is extremely flammable. Helium, on the other hand is completely nonflammable. Aside from hydrogen no other gas is anywhere near as light as helium.
A star is comprised mostly of what two elements?
H Hydrogen which is the lightest element that is highly flammable element and He Helium the second lightest element with no fire risk. This is why helium is used in making balloons than hydrogen which is much lighter than helium.
What chemical property of helium makes it a better choice than hydrogen for use in airships?
It's very light (only hydrogen gas is less dense than helium), it's relatively cheap, and (most importantly) it's not flammable (hydrogen gas is--the Hindenburg was filled with hydrogen gas).
What is heliums specific gravity?
helium doesn't have a specific gravity
Why is helium lighter than nitrogen?
Your question is wrong because hydrogen is the lightest gas but other than that its the lightest nobel gas, and that's just cause its atoms don't have much to them, and neither dose its molecules. With an atomic mass of 2, its the second lightest substance there is, and therefore attracted by gravity the second least of anything, so its gonna be ontop of all other matter (exept hydrogen which has the atomic mass of one)
