Back

Increase in volume when heated. Example: Metal expands when hot.

Front

What is contraction? Give an example.

Back

Decrease in volume when cooled. Example: Balloons shrink in cold air.

Front

What is the difference between heat and temperature?

Back

Heat is energy transfer; temperature measures particle energy.

Front

What happens to particles when heated?
