Question

What is anomalous expansion of water ????​

Answer 1

Answer:

A common observation seen in the behaviour of the substances is that they expand when heated as the density decreases and vice versa takes place when the material is cooled. The density of water gradually increases as you cool it. ... When you reach 4oC, it's density reaches a maximum

Answer 2

Answer:

The anomalous expansion of water is an abnormal property of water whereby it expands instead of contracting when the temperature goes from 4o C to 0o C, and it becomes less dense. ... The density becomes less and less as it freezes because molecules of water normally form open crystal structures when in solid form.
