Phase Diagrams The relationships among the solid liquid and vapor states (or phases) of a substance in a sealed container can be represented in a single graph. The graph is called a phase diagram. A phase diagram gives the conditions of temperature and pressure at which a substance exists as solid liquid and gas (vapor).

We define the equilibrium solution/point for a homogeneous system of differential equations and how phase portraits can be used to determine the stability of the equilibrium solution. We also show the formal method of how phase portraits are constructed.
