During the winter months, water on the surface of a pond will typically freeze and this ice acts as an insulator for the water b
eneath it. As a result, aquatic life is able to survive during the cold winter. The reason that this water expands upon freezing is due to A) the hydrogen bonding that creates its hexagonal shape. B) water molecules being soluble in any polar solvent. C) it's really high heat of vaporization. D) low molecular mass.
When water freezes, the hydrogen bonding that creates its hexagonal shape causes the water molecules to expand out and take up more volume. As a result, its less dense than liquid water and it floats.
B: Newton's law states "any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them." Which is true.
