Exercises:
Sketch the phase diagram of a substance with the following points on the phase diagram: a triple point at 0.5 atm and 150 K; a normal melting point at 175 K; a normal boiling point at 350 K; and a critical point at 2.0 atm and 450 K. The solid liquid line is “normal” (meaning positive sloping).
1. Label the area 1, 2, and 3, and points T and C on the diagram.
2. Describe what one would see at pressures and temperatures above 2.0 atm and 450 K.
3. Describe the phase changes from 50 K to 250 K at 1.5 atm.
4. What exists in a system that is at 1 atm and 350 K?
5. What exists in a system that is at 1 atm and 175 K?
Sketch the cooling curve of a substance with the following points: (A) 85 OC and 0 min, (B) 60 OC and 2 min, (C) 60 OC and 5 min, (D) 20 OC and 8 min, and (E) 20 OC and 11 min. Label each line 1, 2, 3, and 4 and each point A, B, C, D, and E.
1. What phase(s) exist at each of the numbered sections?
2. At what…
