Helium is important because it is used to raise balloons of the ground to often defy gravity
answ2. This gas has the low temperature record - it does not freeze - and is used extensively as a coolant in MRI machines, and Cryogenics in general.
answ 3 - Helium is used in fuel rods of CANDU reactors to fill the gap between uranium dioxide and zircaloy 4
- Gas for leak detection
- Welding in inert atmosphere
- Inert atmosphere for the preparation of special alloys, metals, semiconductors etc.
