Question

Is there a substitute for helium?

Answer 1

Explanation:

Argon is a substitute for helium gas.

Argon: Argon($\mathrm{Ar}$) is a chemical element in group eighteen of the periodic table.

1. It is the 3rd most abundant gas in the Earth's atmosphere, and it is a noble gas.
2. Apart from nitrogen and oxygen, the most common gas in the atmosphere is argon.
3. Argon, like helium, is a noble gas, which means it is completely inert.
4. It is an odourless, colourless gas that does not react with anything else.
5. Despite being a gas, argon can form some compounds under extreme conditions.
6. It is distinguished by the fact that it has the same solubility level as oxygen in the water.
7. Thermal conductivity is low.

Hence, Argon is a substitute for helium.
