Chapter 17, Problem 78PP

Because some pathogens can survive 120°C temperatures, medical autoclaves typically operate at 3 atm pressure, where water boils at 134°C. Based on this information and that given in the preceding problem, you can conclude that

1. a. Fig. 17.9’s depiction of the liquid-gas interface for water is correct in being concave upward.
2. b. Fig. 17.9’s liquid-gas interface should actually be concave downward.
3. c. autoclaves operate above the critical point.
4. d. at its operating temperature, there can’t be any liquid water in the autoclave.
