Chemistry Videos Unit 3: Phases of Matter

Unit 3 is a beast in the course (by which I mean the longest unit), and the videos for this unit demonstrate as much, being more than both unit 1 and unit 2 combined!

Units 4-6 are ready to go from a presentation standpoint, but upcoming vacations will delay the recording until the end of July.
