(a) Describe the phases present in the equilibrium system and their masses.
(b) Describe the changes that occur at constant pressure if the system is placed in thermal contact with a heat reservoir at 30°C.
(c) Describe the changes that occur if the temperature is raised from 25°C to 120°C at con- stant pressure.
(d) Describe the system after 200 g H2O is added at 25°C.
