Multiple Choice

According to the phase diagram given,which of the following statements is INCORRECT?

A) At the temperature and pressure of point 1,W exists as a three-phase equilibrium system.
B) At the temperature of point 2,a pressure of 500 Torr will cause W to liquefy.
C) If the system is maintained at the temperature of point 3 while pressure is decreased,more W will vaporize.
D) If W is maintained at the pressure of point 4 while the temperature is increased to 80 °C,the liquid will vaporize.
E) The existence of liquid W at -40 °C and 500 Torr represents the metastable condition of "supercooling."
