Question

A small nail may pierce an inflated tyre and remain there without pressure reduction in the tyre. Explain the observation

Answer 1

so, Rubber is elastic and when a nail is pushed through it, it stretches and grips the nail firmly without allowing air leakage

2.This is due to the valve effect i.e. pressure from inside causes the tyre rubber to press firmly on the nail, resulting to no air leakage
