Paheli had bought a new bottle of pickle from the market. She tried to open the metal cap to taste it but could not do so. She then took a bowl of hot water and immersed the upper end of the bottle in it for five minutes. She could easily open the bottle now. Can you give the reason for this?

Answers (1)

On immersing the metal cap in hot water, the size of the cap expands. Hence it can be removed easily.
