C) Ph changes from a solid to a liquid as one follows the line from C to D. D) Point B represents the critical temperature and pressure for Ph. E) Like CO2,Ph does not experience the liquid state at atmospheric pressure. ) If a sample of Ph begins at point D and the pressure is increased, the sample will condense when it hits the line that joins points A and B
