Uses of helium: balloons, lasers, protective atmosphere, welding, leak detection, MRI, filling gas in nuclear fuels, physics experiments, etc.
its the 2nd element on the periodic table and it makes things lighter, such as helium balloons, which float as helium is lighter than air
Helium is inert whereas hydrogen is flammable and under some conditions explosive
So far, we can't be sure that aliens exist. If they are technologically advanced, they have probably found some use for helium.
helium balloons
You can use air but it won't float so I would recommend helium. If you suck in helium, it will make your voice sound weird.... Try it!!
What is doubtless the most common use of helium by the elderly is the getting and giving of helium balloons. "Older" people don't do a lot of mixed gas diving, inert gas welding or other activities like that.
Helium is lighter than air, hence it will rise up in air, making things fly.
No, helium is not used in fire extinguishers. We find carbon dioxide (CO2) in some extinguishers, but not helium.
I don't know if you would call this interesting. It takes up7% of the worlds natural air.
helium is used for excitation of neon atoms in helium neon laser..
Some use hot air (like a hot air balloon) and others use helium.
It helps things float. Like blimps.
