Ice has a cage-like structure with vacant spaces,making it less dense than water.

Vedclass · Answer

(B) Generally,solids have a higher density than liquids. However,water is an exception.When water freezes to form ice,the molecules arrange themselves in a specific cage-like structure due to hydrogen bonding.This structure creates vacant spaces between the water $(H_2O)$ molecules.Because of these vacant spaces,the volume of ice increases for the same mass,which decreases its density compared to liquid water.Since ice is less dense than liquid water,it floats on the surface.

Liquids generally have lower density compared to solids. However,you must have observed that ice floats on water. Why does this happen?
