Why Ice cubes float over water?

question : Why Ice cubes float over water?
Answer : usualy solids have more weight than liquids.
If we take 2 things seperately, like take 1 kg of water and 1 kg of ice, you will find that evevthough mass is same ice occupies larger volume.
water is made up of hydrogen & oxygen, molecules of hydrogen and oxygen are bound together by valancy bounding.
hydrogen and oxygen are having different properties like
oxygen atoms have more affinity towards electrons than hydrogen atoms.
the oxygen atom in a water molecule has a slightly negative charge
and the hydrogen atoms have a slightly positive charge.
So water molecules which are closer to each other are through the slightly negatively charged oxygen atoms and the slightly positively charged hydrogen atoms.
this is nothing but hydrogen bonding.
Ice has a diamond structure due to the hydrogen bonding.
Water does not have such an orderly structure, but water molecules are squeezed close to one another because of the hydrogen bonding.
There is more space in ice than in water!
This is the reason why ice is lighter than water. Therefore, ice can float on water.
Ice floats because it is about 9% less dense than liquid water. In other words, ice takes up about 9% more space than water.

When water is in its solid state (ice), the water molecules are packed close together preventing it from changing shape. Ice has a very regular pattern with the molecules rigidly apart from one another connected by the hydrogen bonds that form a crystalline lattice. These crystals have a number of open regions and pockets making ice less dense than liquid water. This is why ice floats on water. Ice forms when the temperature is below freezing (0°Celsius or 32°Fahrenheit).
