Properties of Liquids, Solids, and Solutions

• The Phase Diagram of t-Butyl Alcohol

2
Important Terms To Know

• Vapor Pressure the partial pressure of a gas in
  equilibrium with liquid
• At equilibrium and at constant temperature, the
  pressure has a constant value called the vapor
  pressure of a liquid.
• Vaporization the change of a liquid to a gas
  (evaporation)
• Normal Boiling Point the temperature at which
  boiling occurs when the external pressure is
  equal to 1atm

More Terms

• Phase Diagram a plot showing the effects of
  pressure and temperature on the physical state of
  a substance

More Terms

• Phase Diagram a plot showing the effects of
  pressure and temperature on the physical state of
  a substance
• Triple Point the point at which all three
  phases, solid, liquid, and gas are at equilibrium
• Bernoullis Principle the pressure adjacent and
  perpendicular to a flowing fluid is less than the
  pressure in the direction of flow (planes flying)

Triple Point Procedure Notes

• Check all tubing for broken glass
• Small pieces of glass in the tubing will not
  allow you to get a vacuum.
• Wipe off all glycerin from the thermometer
• Glycerin in your alcohol may change the triple
  point.
• Check that the stopcock has properly clamped the
  tubing
• No suction after the stopcock is closed
• Always break the vacuum before turning off the
  water
