The normal boiling and freezing points of substance X are 87.3 K and 84.0 K respectively. The triple point is at 82.7 K and 0.68 atmosphere. a. Draw a phase diagram for substance X. Label the regions in which the s,l, and g phases are stable. On the diagram, show, show the position of the normal boiling point. b. Describe any changes that can be observed in a sample of solid substance X when the temperature is increased from 40 K to 160 K at a constant pressure of 0.50 atm. c. Describe any changes that can be observed in a sample of liquid substance X when the pressure is reduced from 10 atm to 1 atm at a constant temperature of 100 K (below the critical temperature). d. Does the liquid phase of substance X have a density greater than, equal to, or less than the density of the solid phase? Explain your answer, using the above information.
