Phase Diagrams show what effect temperature and pressure have on a pure substance in a closed system without any air.
Concept #1: The Properties of the 3 Phases of Matter
Concept #2: Understanding the Phase Diagram
The phase diagram looks at the transition of matter between the phases of solid, liquid and gas as temperature and pressure are affected.
