Consider a gas in a container with a movable piston. What happens to the gas particles if the piston is moved to decrease the volume of the container? What happens to the pressure if the piston is moved to give one-half of the original volume of the cylinder? In the blank circle, show the arrangement of atoms when the volume decreases by one-half.
