Two balloon are filled with equal moles of hydrogen and helium. Which balloon will contract first if holes of same size are made in them?

Text Solution

Verified by Experts

The balloon filled with hydrogen gas will contract first
`(r_(H_(2)))/(r_(He))=sqrt((M_(He))/(M_(H_(2))))`
Since the molecular mass of hydrogen is less, it will diffuse faster than helium.
