Question

liquid generally have lower density as compared to solid but you must have observed that ice float on water why

Answer 1

when water is cooled actually it becomes less denser when it freezes into ice and due to lesser density it floats on water.
this behaviour is not shown by others as water is different because of hydrogen bonding... so the heavier water displaces the lighter ice. hence ice floats.
hope it helped !!!!!

Answer 2

Answer: Ice(solid state) is expected to be heavier than water( liquid state) but its lighter and floats over Water. when water in liquid state undergoes freezing volume increases and hence density decreases.

density =mass by volume.

Ice is solid but its density is lower than water due to its structure, the molecules of ice make a cage like structure with lot of vacant spaces. this makes ice floats on water.

Explanation: the structure of ice is more porous than that water that is ice floats in water.
