Question

in winter,the pipelines carrying water burst in cold countries​

Answer 1

Explanation:

1. In cold countries, in winter the temperature of the atmosphere falls below 0°C. When the temperature of water falls below 4°C it expands.
2. As there is no room for expansion, water (or ice) exerts a large pressure on the pipes. Hence the pipelines carrying water burst.
