PHYS 212 Study Guide for Unit I (Thermodynamics)

The purpose of the study guide is to point out the most important terms, concepts, and principles.

It is not an all inclusive panacea. The study guide is not a replacement for your lecture note and/or you text book. Please review you notes and at least the end of the chapter summaries. You should also review sample problems done in the lecture as well as in the book You should also review your homework and recommended problems. The course emphasizes problem solving.
