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.

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.

Which statement describes all solids?

They contain loosely packed atoms.

They have a definite shape and volume.

They have a smooth, rigid surface.

They flow with resistance.

Density describes how much mass is contained in a certain volume. Knowing how far apart molecules are in each state, which best ranks solids, liquids, and gasses from least dense to most dense?

Gasses are denser than liquids.

Liquids are denser than solids.

Gasses are less dense than solids.

Solids are less dense than liquids.

Which statement best describes the atoms of the gas neon?

They slide past each other.

They move freely in all directions.

They vibrate in place.

They are packed closely together.

Which statement best describes the atoms in a gas?

They vibrate in place.

They stay in a fixed position.

They are closely packed.

They move freely in all directions.

Carmen has a sample of matter. It is clear and smells sour. The sample is also thick but it flows when poured.Which is the best conclusion about Carmen’s sample?

It is a liquid because it is clear.

It is a liquid because it flows.

It is a solid because it is thick.

It is a solid because it smells sour.

Which best describes why a liquid needs a container when a solid does not?

Solids fill their containers, and liquids have definite shapes.

Solids have definite shapes, and liquids fill their containers.

Solids particles will expand to fill their containers, and liquid particles will expand as well.

Solids particles expand to fill their containers, and liquid particles do not.
