  1. Boiling Point Notes Solid Liquid Gas

  2. Today’s Objective • SWBAT: Analyze what boiling point is and how it applies to the lab we completed.

  3. Vaporization • Vaporization – change from liquid to gas • Vaporization happens when particles in a liquid gain enough energy to form a gas. Increasing Thermal Energy Gas Liquid Boiling point

  4. Two Kinds of Vaporization • Evaporation – vaporization that takes place only on the surface of the liquid • Boiling – when a liquid changes to a gas BELOW its surface as well as above.

  5. Boiling Point • Boiling Point – temperature at which a liquid turns into a gas. • Each pure substance has a SPECIFIC boiling point. • Examples: • B.P. of Water = 100°C (212°F) • B.P. of Nitrogen = -195.79 °C (-320.42 °F) • B.P. of Silver = 2162 °C (3924 °F) • B.P. of Carbon = 4027 °C (7281 °F)

  6. Boiling Point and Melting Point Boiling point Melting point

  7. Boiling Point Lab • Think about the lab, did the two volumes of liquid have a different boiling point? Why? • No, because they were both water. • It doesn’t matter how much water you have it will still boil at 100 deg C. • However, it will take longer for a larger volume to boil than a smaller one.

  8. Boiling Point Lab • Why did we place the test tube in a beaker of cold water? • The water vapor traveled through the tube and CONDENSED when it hit the cold test tube turning back into water.
