A sample of water ice at atmospheric pressure has a temperature just below the freezing point. Refer to Figure 17-28 to answer the following questions, (a) What phase changes occur if the temperature of the system is increased while the pressure is held constant? (b) Suppose, instead, that the temperature of the system is held constant just below the freezing point while the pressure is decreased. What phase changes occur now?
