Chapter 11, Problem 11.15P

Conceptual PRACTICE 11.15 Look at the phase diagram of ${\text{H}}_{\text{2}}\text{O}$ in Figure 11.21, and describe what happens to an ${\text{H}}_{\text{2}}\text{O}$ sample when the following changes are made:

(a) The temperature is increased from —25 °C to 50 °C at a constant pressure of 10 atm.

(b) The pressure is reduced from 50 atm to 0.5 atm at a constant temperature of 100 °C.

(c) The pressure is first increased from $\text{6}\times \text{1}{0}^{–\text{3}}$ atm to 5 atm at 50°C, and the temperature is then increased from 50 °C to 375 °C.
