Question

Anomalous expansion of water?

Answer 1

Answer:

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

Answer 2

Answer:

Water has a anomalous expansion by which it contracts on cooling like any other liquid until the temperature of 4 degrees celcius and then begins to expand until 0 degrees celcius. This is why the volume of ice of a certain mass is more than the volume of water of the same mass.
