Question

Liquids have lower density than solid. Bit ice floats on water .why

Answer 1

it is because water shows anomalous expansion and when cooled between 4 C to 0 C, i.e it expands in volume. So density of ice becomes less than the density of water at 4 C due to which it floats on water.

Answer 2

ICE FLOATS ON WATER BECAUSE IT HAVE LOWER DENSITY THAN WATER BECAUSE AIR MOLECULE GET TRAPPED INSIDE THEM BECAUSE OF THE SHAPE OF BONDING BETWEEN THEM THE SHAPE HAVE AN CUBICAL HOLLOWNESS WHERE AIR GET IN AND MAKE ICE LIGHTER
