PHASE DIAGRAMS

PHASE DIAGRAM

• A representation of the phases of a substance in
  a closed system as a function of temperature and
  pressure

3
Normal Boiling Point

• Temperature at which the vapor pressure of the
  liquid is exactly 1 atmosphere

4
Normal Melting Point

• Temperature at which the solid and liquid states
  have the same vapor pressure when the total P 1
  atm

5
Triple Point

• The point on a phase diagram at which all three
  states of a substance are present

6
Critical Temperature

• Temperature above which vapor cannot be liquified
  no matter what pressure is applied

7
Critical Pressure

• Minimum pressure required to produce liquefaction
  of a substance at the critical temperature

8
Critical Point

• Ordered pair of
• Critical Temperature
• Critical Pressure
