Question

Why the Cycles needs a refill of air in Tyre? class 7​

Answer 1

Explanation:

This is due to its larger molecule size which makes it extremely hard for nitrogen to leak out of the tyre. In comparison, air filled tyres have smaller molecules of oxygen, inert gases and water vapour that leak out easily and hence require to be refilled more frequently.
