Water pipes in colder countries often burst in winter?

Explain the following……

1-Water pipes in colder countries often burst in winter.

   Ans-In winter nights, as the atmospheric temperature starts falling below 4 C, water in pipe lines expands and it exerts large pressure on the pipe , causing them to burst. Plants also die for the same reason as their capillaries burst when water expands below 4 C.

ANOMALOUS EXPANSION OF WATER:

If we take some water at 0⁰ C and start heating it, we find that it contracts in the temperature range from 0^o C to 4^o C. On heating it further above 4^o C, it expand . Similarly, it water initially at a temperature above 4^o C is cooled , it contracts till the temperature of water reaches 4^o  C. On further cooling it below 4^o C to 0^o C, its expands. This unusual expansion of water on cooling it in the temperature range 4^o C to 0⁰ C is called anomalous expansion of water
