  1. Liquids & Solids Dr. Ron Rusay Fall 2001

  2. States of Matter

  3. Changes of State

  4. Energy of Phase Changes

  5. Heating Curve for H2O

  6. Vapor Pressure vs. Temperature

  7. Vapor Pressures of Liquids

  8. Periodicity: Boiling Point Boiling Point: Temperature at which the vapor pressure of the liquid equals the atmospheric pressure. Higher vapor pressure : Lower boiling point.

  9. Boiling Points of Simple Hydrogen Compounds What can explain the trends?

  10. Intermolecular Hydrogen Bonds in H2O Besides oxygen, both nitrogen and fluorine form intermolecular hydrogen bonds. Other atoms DO NOT.
