Question

state the uses of helium?​

Answer 1

Answer:

Helium is used as an inert-gas atmosphere for welding metals such as aluminum; in rocket propulsion (to pressurize fuel tanks, especially those for liquid hydrogen, because only helium is still a gas at liquid-hydrogen temperature); in meteorology (as a lifting gas for instrument-carrying balloons); in cryogenics

Answer 2

Answer:

Uses of helium are-

1) Used to provide an inert protective atmosphere.

2) For making fibre optics and semiconductors, and for arc welding

3) Used to detect leaks, such as in air conditioning systems.

4) Because it diffuses quickly, it is used to inflate car airbags after impact.
