1. Intentions for success:
We will be successful when we can define the types of phase changes in matter
Aug. 30, 2018
Vocab: Sublimation, Vaporization, Endothermic, Exothermic
Warm up: Table salt is solid at room temperature and Acetone is a liquid at room temperature. What can we conclude about the melting points of these materials?

Ch. 8 - Solids, Liquids, & Gases
II. Changes in State (p.84-86)
Phase Changes
Heating Curves

4. melting point = freezing point
A. Phase Changes
Melting
solid to liquid
Freezing
liquid to solid
melting point = freezing point

5. A. Phase Changes Vaporization (boiling)
liquid to gas at the boiling point
Evaporation
liquid to gas below the boiling point
Condensation
gas to liquid

6. A. Phase Changes Sublimation solid to gas
EX: dry ice, freeze drying, iodine

8. A. Phase Changes

9. B. Heating Curves Kinetic Energy motion of particles
related to temperature change
Potential Energy
space between particles
related to phase changes

10. B. Heating Curves Gas - KE  Boiling - PE  Liquid - KE 
Melting - PE 
Solid - KE 

11. B. Heating Curves Look at the Graph
What happens to the temperature during a phase change?
What happens to the arrangement of molecules between phase changes?

12. B. Heating Curves Heat of Fusion
energy required to change from solid to liquid
some attractive forces are broken

13. B. Heating Curves Heat of Vaporization
energy required to change from liquid to gas
all attractive forces are broken
EX: steam burns, sweating, and… the drinking bird
Compare Evaporation and Vaporization
