Question

2. To fit a wooden handle in the iron ring of a tool to dig soil, the ring is heated.
What will be the change in volume of the Ring.​

Answer 1

The iron blade of soil digging tools has a ring in which the wooden handle is fixed. Normally, the ring is slightly smaller in size than the wooden handle. To fix the handle, the ring is heated and it becomes slightly larger in size (expands). Therefore, the handle easily fits into the ring.
