Problem: Imagine a substance with the following points on the phase diagram: a triple point at .5 atm and -5°C; a normal melting point at 20°C; normal boiling point at 150°C; and a critical point at 5 atm and 1000°C. The solid liquid line is "normal" (meaning positive sloping). For this, complete the following: 1. Describe what one would see at pressures and temperatures above 5 atm and 1000°C. 2. Describe what will happen to the substance when it begins in a vacuum at-15 °C and is slowly pressurized. 3. Describe the phase changes from -80°C to 500°C at 2 atm.
