• Solid and Liquid
• Gas only

• Tomato Sauce

How do materials change from one state of matter to another?

• They gain or lose energy
• They break appart

Gold is a dense solid. What does this mean?

• It is hard

• It is heavy

• It is heavier than other things of the same size

• It is malleable

What is the equation for density?

• Density = mass x volume

• Density = weight x volume
