WebThe shape of a phase diagram is almost the same for each pure substance. Several phases can coexist if the pressure and temperature conditions are on the phase separation curve. The most common example is an ice cube in a glass, if the temperature between the liquid and the solid is precisely 0°C and the air is also at 0°C, then their state ...

Critical point (thermodynamics) - Wikipedia

WebThese are easy! Suppose you have a pure substance at three different sets of conditions of temperature and pressure corresponding to 1, 2 and 3 in the next diagram. Under the set of conditions at 1 in the diagram, the … For simplicity and clarity, the generic notion of critical point is best introduced by discussing a specific example, the vapor–liquid critical point. This was the first critical point to be discovered, and it is still the best known and most studied one. The figure to the right shows the schematic PT diagram of a pure substance (a… WebTemperature Entropy (T-s) Diagram.
