Key Concepts

Thermodynamic Equilibrium

Thermodynamic equilibrium is a state in which a system’s properties are balanced and remain constant over time, with no net change in phase or energy. In the context of phase diagrams, the equilibrium lines represent the conditions under which multiple phases can exist simultaneously because the system is in a state of equilibrium.

Phase Transitions

Phase transitions refer to the changes between different states of matter that occur when conditions like temperature or pressure vary. In a phase diagram, these transitions are depicted as lines or curves, each representing the set of conditions where two phases coexist in equilibrium.

Phase Diagram

A phase diagram is a graphical representation that shows the stable phases of a substance under different conditions such as temperature, pressure, and composition. It identifies the regions where distinct states of matter (solid, liquid, gas, etc.) exist and illustrates the equilibrium boundaries at which these phases transition from one form to another.
