Fishes living in lakes which are prone to freezing in winter, take advantage of this property of water ( having greatest density at 4 degree celsius).
When temperature starts reducing in winter, lake water cools upto 4degree celsius by convection as density increase with reduction in temp.
On further cooling, due to abnormal expansion of water , density reduces & cold water remains at top .Then top layer frezees.Water being bad conductor of heat ,lake water below ice remains at 4 degrees & thus fishes can survive in winter also.
Water has the greatest density at 4ºC or 39.2ºF
Fresh water achieves its greatest density (999.9720) at 4 degree Celsius and the lowest density (958.4) at 100 degree Celsius. The other details are given below. 100-958.4,80 - 971.860-983.240-992.230-995.650225-997.047922-997.773520-998.207115-999.102610-999.70264-999.97200-999.8395−10-998.117−20-993.547−30-983.854
