Question

b) Define anomalous expansion of water in phyi​

Answer 1

• Anomalous expansion of water is defined as the expansion of water when it is cooled from four degree celsius to zero degree celsius.

• Volume and density of water changes in different ways when heated from zero degree celsius to ten degree Celsius

The volume of water first decreases on heating it from zero degree celsius to four degree celsius and is minimum at four degree celsius.

On further heating the water above four degree celsius, the volume starts to increase.
