Thermal Expansion Quiz

What is thermal expansion?

• Change in density due to pressure

• Change in color due to temperature

• Change in state from solid to liquid

• Change in shape, area, and volume in response to a change in temperature

What are the effects of thermal expansion on solids?

• Thermal expansion causes solids to expand.

• Thermal expansion causes solids to shrink.

• Thermal expansion has no effect on solids.

• Thermal expansion causes solids to change color.
