Answer to Question #182472 in General Chemistry for elysha

Question

Illustrate the phase diagram of a substance given with the following points: a triple point at 0.70 atm and 80 ºC; a normal freezing point at 100 ºC; a normal boiling point at 350 ºC; and a critical point at 1.6 atm and 810 ºC. For this, complete the following:

1. Roughly sketch the phase diagram, using units of atmosphere and degree Celsius. 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 1.25 atm and 300 ºC.

3. Describe the phase changes from 100 ºC to 200 ºC at 1.5 atm.
