Why is helium preferred to hydrogen for filling balloons?

Answered by admin @ 23/08/2021

This is on the grounds that helium is less thick. Since helium is lighter than air, a helium expand rises. Hydrogen is another gas lighter than air; it is significantly lighter than helium. Hydrogen isn't utilised in inflatables and this exhibit indicates why Helium is preferred to hydrogen for balloons. Hydrogen is lighter, however it responds dangerously with oxygen. Helium is totally inactive at typical conditions.
