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

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