HERE 's UR ANSWER

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