Library of Conceptual Questions (CQs): Phase Changes
Draw a rough graph that shows how the pressure changes inside a cylinder of carbon dioxide at a pressure of 65 atm and a temperature of 20oC, as gaseous carbon dioxide is released from the cylinder at constant temperature.

Draw a similar graph for CO2 at 40 oC.

(This question requires the critical temperature of carbon dioxide be given somewhere else on the exam.)
