Referring to Figure, describe all the phase changes that would occur in each of the following cases:
(a) Water vapor originally at 0.005 atm and -0.5 °C is slowly compressed at constant temperature until the final pressure is 20 atm.
(b) Water originally at 100.0 °C and 0.50 atm is cooled at constant pressure until the temperature is -10 °C.
