1. WARM UP
How do intermolecular forces impact the temperatures at which phase changes occur?

2. Phase Properties

3. IMF and Physical Properties
Viscosity, surface tension, cohesion, and adhesion all increased with increasing IMF

4. IMF and Phase Changes Solid – Liquid Melting and Freezing
Melting Point
Higher based on intermolecular forces

5. IMF and Phase Changes Liquid – Gas Vaporization and Condensation
Boiling point
Higher with increasing mass and intermolecular forces

6. IMF and Phase Changes
Solid – Gas
Sublimation and Deposition

7. WRAP UP

Which of the following should have the lowest melting point?
a. Br2 b. KCl c. NaOH

8. WARM UP “Pack your own parachute.” – T.L. Hakala
