You have a sample of gas in a container with a movable piston, such as the one in the drawing.
(a) Redraw the container to show what it might look like if the temperature of the gas is increased from 300 K to 500 K while the pressure is kept constant.
(b) Redraw the container to show what it might look like if the external pressure on the piston is increased from 1.0 atm to 2.0 atm while the temperature is kept constant.
(c) Redraw the container to show what it might look like if the temperature of the gas decreases from 300 K to 200 K while the pressure is kept constant (assume the gas does not liquefy).
