30. Phase Change Diagrams: Draw & Label this example Phase Diagram

31. Phase Diagrams  A phase diagram is a graphical way to depict the effects of pressure and temperature on the phase of a substance.  The curves indicate the conditions of temperature and pressure under which equilibrium between different phases of a substance can exist.  Melting/Freezing point  Vaporization/Condensation point  Sublimation/Deposition point  Triple Point = where all 3 phases of matter exist

32. Phase Diagrams  The Critical Point is where the vapor pressure curve ends, it’s the point where the substance can no longer exist as a liquid, only as a gas.  STP = Standard Temperature and Pressure  = 0 degrees Celsius = 273 Kelvin  = 1.00 atm (air pressure at sea level)
