Answer 2

Answer: Water expands on reducing its temperature below 4°C.

Explanation:

Water contracts when its temperature is reduced, however, it reaches the maximum density at 4°C. On reducing the temperature further from 4°C to 0°C, it expands.

This phenomenon is known as anomalous expansion of water. It is an abnormal property of water wherein it starts becoming less dense after 4°C.
