Question

In winter , the pipelines carrying water burst in cold countries .
Give scientific reason .​

Answer 1

Answer:

water when is being cooled gets expanded instead of contracting (4 - 0 degrees) due to which the pipeline burst

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 pipelines carrying water burst.

Hope it helps!
