2023年1月30日 · 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.
Phase Changes of Matter (Phase Transitions)
2020年10月8日 · 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.

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).

2023年12月13日 · The energy changes that occur during phase changes can be quantified by using a heating or cooling curve. Heating Curves Figure \(\PageIndex{3}\) shows a heating curve, a plot of temperature versus heating time, for a 75 g sample of water.

Use phase diagrams to identify stable phases at given temperatures and pressures, and to describe phase transitions resulting from changes in these properties. Describe the supercritical fluid phase of matter. In the previous module, the variation of a liquid’s equilibrium vapor pressure with temperature was described.
