|
|
The increased number of hydrogen bonds in ice compared to liquid water causes the water molecules in ice to be closer together
|
|
|
The ice molecules have higher kinetic energy than the liquid water molecules, causing them to float
|
|
|
The crystalline structure of solid ice due to hydrogen bonds makes it less dense than liquid water
|
Detailed explanation-1: -As water freezes, the molecules form a crystalline structure that spaces the molecules further apart than in liquid water. This means that ice is less dense than liquid water, which is why it floats.
Detailed explanation-2: -Because ice is less dense than water, it is able to float at the surface of water.
Detailed explanation-3: -The ice float on water because its density is less than water.
Detailed explanation-4: -Hydrogen bonding gives ice a rather open type structure with wide holes whereas; structure of water didn’t give any free space in the molecular structure. This gapping in the structure reduces density and increases volume. Hence, the density of ice is less than that of water and therefore it floats on water.
