Question

liquid have lower density as compared to solids but ice float on water find why?

Answer 1

Yes it's true that density of solids are generally greater than liquids.But ice floats on water!This is the reason why aquatic lives exist in very low temperature .

This is very interesting . Water is a very special molecule i.e it has tendency to form hydrogen bonds which is the cause of existence of life on Earth.

Ice has cage like structure in which a large portion in between is vacant , imagine a cage .

That is why its density is less than water . Hence, it floats in water .

Density of water = 1 g/cm3

Density of ice = 0.9 g/cm3

Liquid generally have lower density as compared to solids but ice floats on water. why?

$\large\green{\underline{\underline{\mathscr{\red{\:\:\:\:\:Answer\:\:\:\:\:}}}}}$

Density of ice is less than the density of water.The low density of ice can be attributed to the small pores it was which allows it to trap air.Hence ice floats on water.
