Question

why ice floats on water

Answer 1

Hey there!!


=>> Though ice is a solid, it has large number of empty spaces between its particles. These spaces are larger as compared to the spaces present between the particles of water, giving ice a cage like structure. Thus, due to the empty spaces the volume of ice is greater than same mass of water. Hence, the density (mass per unit volume) of ice is less than that of water. A substance with lower density than water floats on the surface of water. Therefore, ice floats on water.


Hope it helped!!!!☺️

Answer 2

As it cools further and freezes into ice, it actually becomes less dense. On the other hand, most substances are most dense in their solid (frozen) state than in their liquid state. Water is different because of hydrogen bonding. ... The heavier water displaces the lighter ice, so ice floats to the top.
