Question

give reason. water pipe in colder countries often burst in winter

Answer 1

Water pipes burst because the water inside them expands is it gets close to freezing, and this causes an increase in pressure inside the pipe. When the pressure gets too high for the pipe to contain, it ruptures.

Answer 2

$\large\boxed{\fcolorbox{blue}{yellow} {Answer}}$

1. In cold countries, in winter, the temperature of the atmosphere falls below 0∘C.

2. When the temperature of water falls below 4°C, it expands.

3. As a result, the water in the pipes expands.

4. Even if ice is formed, there is an increase in the volume.

5. As there is no room for expansion, water (or ice) exerts a large pressure on the pipes.

Hence, the pipes carrying water often burst.
