Question

Why ice can float on water?

Answer 1

The density of ice is lower than water and it also have large surface area therefore ice floats on water.

Answer 2

hey mate!!
here is ur ans_________________________
____________________________________
Unlike water,ice has a different structure all together. X-Ray crystallography study show that ice has hexagonal three dimensional crystal structure formed by intermolecular hydrogen bonding which leaves almost half of the space vacant unoccupied.

Water has a Tetrahedral geometry where as ice has hexagonal geometry.



As u can see from the above image, the structure of water is very compact where as the structure of ice is loose having spaces in between. Due to the compact structure water has a greater density as compared to ice. This is the reason why ice floats on water.
