2. Pipelines in cold countries often burst in winter, because A.Water freezes and expands in its volume B.Temperature of ice is less than that of water C.Pipelines contract in their volume D.Pipelines expand due to freezing
Option A Solution: Water in pipes freeze in cold countries. Due to the anomalous expansion of water, it expands instead of contacting when there is a fall in temperature below 4°c. So, the water pipes burst due to the excess space consumed by the ice after freezing.
