Crystalline solids and amorphous solids are different in that crystalline solids have a well-ordered structure, while amorphous solids do not. What do they have in common?

• Both have a definite shape and volume.

• Both have a well-ordered structure.

• Both are liquids at room temperature.

• Both are gases at room temperature.

Match the following states of matter with the molecular movement description:

• Liquids

• Molecules are stationary in solids, move faster in liquids, and move fastest in gases.

• Solids

• Molecules move fastest in solids, slower in liquids, and are stationary in gases.

• Gases

• Molecules move faster in solids, slower in liquids, and are stationary in gases.
