How can we say that ice has more density than water?
Hi Deeksha2309 !
The density of Ice is less than that of water, this is the reason that ice floats on water!!
Intermolecular hydrogen bonding between the H2O molecules at 0 oC becomes stable and stronger as water is cooled below 4 oC. And when the temperature of the water reaches 0 oC or below strong stable hydrogen bonds forms a rigid hexagonal crystal lattice structure. This is also called open cage structure between the water molecules. This makes water solid in form of ice and net space occupied by the molecules increases. Hence, density ice becomes less than that of water and it floats.
