According to the phase diagram given,which of the following statements is INCORRECT?
A)At the temperature and pressure of point 2,substance Z exists as a three-phase equilibrium system.
B)At the temperature and pressure of point 3,substance Z exists as a one-phase gaseous system.
C)If the Z(s)= Z(l)= Z(g)system is maintained at the temperature of point 2 while pressure is decreased,more Z will vaporize.
D)If liquid Z is maintained at the pressure of point 4 while the temperature is decreased to 30 °C,the liquid will vaporize.
E)The existence of liquid Z at -50 °C and 2 atm represents the metastable condition of "supercooling."
