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.

The solid state is the most dense, followed by the liquid state, then the gas state.

b)

The solid state is more dense than the liquid state.
