Question
Explain, why do water pipes burst during severe winter?

Answer

In severe winter, water pipe lines often burst because water freeze at sub-zero temperature and in doing so expands. Since there is no space within the pipes for expanding ice, it exerts very large pressure and bursts open the steel pipes.
