What is density?

• How close or compact the molecules are

• The amount of heat in an object

• The speed at which molecules move

• The color of an object

How does temperature affect density?

• As temperature increases, density decreases

• As temperature increases, density increases

• As temperature increases, density stays the same

• As temperature increases, molecules move closer together
