WebSuppose 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 substance would be a solid because it falls into that area of the phase diagram. At 2, it would be a liquid; and at 3, it would be a vapour (a gas). WebIn other words, these lines define phase change points. The red line divides the solid and gas phases, represents sublimation (solid to gas) and ... a normal melting point at 20°C; a normal boiling point at 150°C; and a …
