Answer 1

The question is not clear but I assume it is-

Give one use of expansion of object on heating

Answer:

To fit the iron rims onto the wooden wheels of carts, the smaller iron rim is heated and thus it expands. This makes it bigger than the wheel and is then fitted onto the wheel. The cold water is poured over it so the rim contracts and returns to its original size and fits tightly onto the wheel.

Hope this answers your question.
