Solution

From about 4 °C to water's freezing point at 0 °C, the molecules are no longer able to so easily slip past each other as they did in the liquid phase. They feel attraction between the hydrogen atoms of one water molecule and the oxygen atoms of nearby molecules. Thus, they begin to take on an orderly crystalline arrangement that we recognize as ice. The ice simply takes up more space than the liquid state. Hence, water expands when it freezes. Further freezing does not affect the size
