HPS Properties of Liquids and Gas/Liquid Solutions

In Class:

• Video of super saturation demonstration (see videos)
  
• Properties of (liquid) solutions:
• freezing point depression
• boiling point elevation
• Solutions of gases in liquids
• dissolving process
• factors affecting solubility of gases in liquids

Homework:

• HPS Notes 7.2: Unit 7 Test Review. Start this in preparation for test on Wednesday.

Videos:
These videos are from the regular physical science class, but cover the same material at the same depth. The pace of presentation in the regular class was a little bit slower.
