The anomalous expansion of water is an abnormal property of water whereby it expands instead of contracting when the temperature goes from 4oC to 0oC, 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.
Water is denser than ice while almost all the other substances are denser in solid form than in liquid form. The maximum density of water occurs at a temperature of 4oC and this is caused by the hydrogen bonding between the oxygen atoms that are negatively charged and the hydrogen atoms that are positively charged, from two different molecules of water.

Anomaly basically in terms of English word is mistake though we don't use this word in spoken English. The Anomalous expansion of water is actually a mistake by nature. when water is cooled down it gradually contracts but to 4°. But between temperature 4° - 0°. Water expands. This is the anomalous expansion of water. Like practically if you see. If you keep a glass full of water overnight in freezer note:- Not in the fridge. Next morning you'll get that glass broken. Also, pour some water in a tray not till the brim. And make a mark and keep it in freezer. You will not be able to see your mark thus it will not be visible.
