Question

What is anomalous behaviour of water?
Please give right answer.​

Answer 1

Answer:

When water is heated from 0°C to 4°C it CONTRACT and density INCREASE, heating water above 4°C starts expanding and density of water decrease. This means water has a maximum density at 4°C. This is called anomalous behaviour of water.

Answer 2

Explanation:

Water does not expand between 0°C to 4°C instead it contracts. It expands above 4°C. This means water has maximum density at 4°C. This is called anomalous behaviour of water.
