t(°C)
a) If liquid Z is maintained at the pressure of point 4 while the temperature is
decreased to 30 °C, the liquid will vaporize.
b) The existence of liquid Z at -50 °C and 2 atm represents the metastable
condition of "supercooling."
c) If the Z(s) = Z(I) = Z(g) system is maintained at the temperature of point 2
while pressure is decreased, more Z will vaporize.
d) At the temperature and pressure of point 3, substance Z exists as a one-
phase gaseous system.
e) At the temperature and pressure of point 2, substance Z exists as a three-
phase equilibrium system.
