Question

Density involves the amount of a material in a certain volume. When a material changes phases, it changes in density in a predictable way as the amount of material stays the same but the molecules get farther apart or closer together.Water has solid and liquid states that do not follow these predictions of density in the phases of matter. What does that mean about the densities of the phases of water? The solid state is the most dense, followed by the liquid state, then the gas state. The solid state is more dense than the liquid state. The liquid state is more dense than the solid state. The gas state is the most dense, followed by the liquid state, then the solid state.

Answer

The liquid state is more dense than the solid state.

Explanation

In most substances, the solid state is denser than the liquid state, as molecules are more tightly packed in solids. However, water is an exception because of hydrogen bonding. In the solid state (ice), water molecules form a crystalline structure maintained by hydrogen bonds, which keeps them farther apart than in the liquid state. Thus, ice is less dense than liquid water, resulting in ice floating on water. The gas state, as expected, is the least dense because the molecules are much farther apart compared to both solid and liquid states.
