• heat

In a tank of air, as the volume __________ the pressure __________.

• increases, increases

• increases, decreases

• decreases, decreases

• decreases, increases

• pressure

• temperature

• volume

• heat

How would the pressure of the gas in an air tank change if more gas particles are added?

• As particles are added the pressure inside the tank would decrease.

• As particles are added the pressure inside the tank would increase.

• As particles are added the pressure on the outside of the tank would increase.

How are pressure and volume related?

• As the pressure decreases, volume decreases.

• As the pressure increases, the volume increases.

• As the pressure increases, the volume decreases.

• As the pressure decreases, the volume stays the same.

Changes in temperature, pressure, and volume affect the behavior of gases more than they

affect solids and liquids.

• True

• False
