Why does the solid phase of water (ice) float in liquid water?
Solid forms of other liquids such as ethanol sink when placed in their corresponding liquid.
Hydrogen bonding is an intermolecular force.
Intermolecular forces are forces of attraction that exist between molecules.
These forces affect the properties of the molecule such as melting point, boiling points and solubility.
For example, the hydrogen bonding in ice causes the arrangement to the water molecules to be more open than normal making the density of ice less than the density of liquid water.
With a smaller density, ice floats!

Answer: SOLID WATER(ICE) IS LESS DENSE THAN LIQUID WATER

Explanation:Water molecules are bonded together by Hydrogen bonds, Hydrogen bonds are intermolecular forces binding the molecules of Oxygen with that of Hydrogen. When in an ICE state,the solid form of water will float on the liquid form of water, because the orientation of Hydrogen bonds pushes or makes the Ice molecules to stay far apart from each making it less Dense than liquid water.
