- #36What do you mean by anomalous behaviour of water ?Ans : Substances when heated expand. Their density [m/v] decrease. But in case of water:
When water is heated from 0°C to 4°C it contract and density increases, heating water above 4°C starts expanding and density of water decrease. This means water has maximum density at 4°C. This is called anomalous behaviour of water.
