Unformatted text preview: When the temperature is raised from 20 C to 45 C at 0.8 atm pressure, what phases will be observed during this temperature change? A. solid " liquid B. solid " gas C. liquid " gas D. solid " liquid " gas E. gas only Solution: 1. From the phase diagram, we see that w represents solid phase, x represents liquid phase, y represents gas phase, and z represents triple point. 2. At 0.8 atm and 20 C, the substance falls in the region of x (liquid phase). At 0.8 atm and 45 C, the substance falls in the region of y (gas phase). Therefore, C is correct answer. ! Answer: C...
