Phase Equilibria definition Equilibrium definition Phase |
Phase equilibrium is the study of the equilibrium which exists between or within different states of matter, namely solid, liquid and gas. Equilibrium is defined as a stage when the chemical potential of any component present in the system stays steady with time. Phase is a region where the intermolecular interaction is spatially uniform. |

Phase Equilibria |
Phase equilibria is the application of the principles of thermodynamics to the study of equilibrium relationships within homogenous phase or between heterogenous phases. key tool in exploring phase equilibria is a phase diagram which is used to show conditions (pressure, temperature, volume, etc.) at which thermodynamically distinct phases (such as solid, liquid or gaseous states) occur and coexist at equilibrium. |

Phase diagram |
used to understand the relationship between different phases and are usually represented as the change in the phase of a system as function of temperature, pressure, or composition of the components in a system. The system exists in a phase where the Gibbs free energy of the system is least. Phase diagram is a graphical representation of the physical states of a substance under different conditions of temperature and pressure. A typical phase diagram has pressure on the y-axis and temperature on the x-axis. As we cross the lines or curves on the phase diagram, a phase change occurs |
