Question

liquids have lower density than solids, then why does ice float on water??

Answer 1

Because ice being a solid has lesser density than a liquid water. This case is an exception.

Answer 2

hye

===================

this is a very easy question

=> wehn water frezzes into ice , some space is created in between them

=>solids have more spaces and voulme than liqiuds

=>so of course  , the volume increases for the  mass of water. as there is empty space in the molecules

we can tell in a different way

=>the density of the  ice is lower than the waters density

∴ 
 ice float on water
