Ice has less density when compared to the water. It is because,
increase in temperature, leads to lower density.
Therefore, the water at that temperature have a density higher than that of the ice, because of the temperature, and the lower inter molecular forces.
Also, water is the only liquid which have higher density than the solids(than the ice only). It is because of the above reasons, and also, ice is not a pure solid, it is an amorphous solid.
