Answer 1

Liquids generally have lower density as compared to solids. But you must have observed that ice floats on water. ... Answer: Ice in fact it is solid but it has cage like structure andhence its molecules have more empty space as compared to water so it has smaller density then water and hencefloats on water.

Answer 2

Due to cage like structure of ice, molecules are not closely packed and vacant spaces are left. As ice melts these molecules come closer and hence the density increases. As ice being less denser it floats on surface of water.
