Phase Changes of Matter (Phase Transitions)
Oct 8, 2020 · At the phase transition, such as the boiling point between liquid and gas phases, the two states of matter have identical free energies and are equally likely to exist. Here is a list of the key phase changes between solids, liquids, gases, and plasma.

Jan 30, 2023 · 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.

Using the graph, if you know the pressure and temperature you can determine the phase of water. The solid lines—boundaries between phases—indicate temperatures and pressures at which the phases coexist (that is, they exist together in ratios, depending on pressure and temperature).

Phase Change Diagrams — Overview & Examples. A phase diagram shows how temperature and pressure affect the phase of a substance. It's made up of regions, curves, a critical point, and a triple point.
