Question

Describe two adverse consequences of the anomalous expansion of water.

Answer 1

Explanation:

The two adverse consequences of the anomalous expansion of water are:

1. Bursting of water pipes during winter: On winter nights, when the temperature starts falling below $4°C$, water in pipelines expands and exerts large pressure on the pipes, causing them to burst.
2. Icebergs floating on water: Generally, the density of solids is greater than that of liquids. But in the case of water, liquid density is greater than the density of ice. Therefore, ice floats on the water surface.
