According to the phase diagram below, which of the following is INCORRECT? 800- U (s) P(tor) 500- HD 400- 200- 1 U() U(g) -20 -10 0 10 20 0 A) At the temperature and pressure of point 1, substance U exists as a three- phase equilibrium system. B) At the temperature and pressure of point 2, substance U exists as a one- phase gaseous system. C) At the temperature and pressure of point 3, substance U exists as a two- phase system. D) If the U(s) U(1) system is maintained at the temperature of point 4 while pressure is decreased steadily to about 300 Torr, more U will freeze. E) There are no conditions of temperature and pressure under which solid U will vaporize without melting first.
