Solids, Liquids, and Gases

An inverse relationship is when:

• both go up or both go down

• one goes up and the other goes down

• sometimes they both go up and sometimes one goes up and the other goes down

• they both only go down

Gas particles......

• are tightly packed and vibrate in place

• are close together but can slide past each other

• are spread apart, moving fast, and change volume very easily

Boyle's law tells us that when volume increases at a constant temperature.........

• temperature decreases

• pressure increases

• pressure decreases

• temperature increases

Charles' Law tells us that when temperature increases at a constant pressure.......

• volume decreases

• volume increases

• pressure decreases

• pressure increases
