Water has a ph value of 10 is made of helium and oxygen becomes less dense when it freezes is unable to dissolve most substances

The answer is C, becomes less dense when it freezes.

The correct answer is : becomes less dense when it freezes.

Explanation:

Water is a polar covalent compound which contains a covalent bond between 2 hydrogen and oxygen atoms. The chemical formula for this compound is

This compound has a pH of 7. The density of water is liquid state is more than the density of water in solid state. Water has a property to expand when it freezes and it forms cage like structure in the solid state. This results in the increase of volume.

Relationship between density and volume is given by:

As, volume is inversely related to the density. Thus, if volume increases, the density decreases.

Hence, Water becomes less dense when it freezes.
