Read chapter 2 entirely, but skim the part absolute entropy and the third law. Please work through the following tutorials:

• Ups and Downs: State Functions

• Shake, Rattle and Roll: a microscopic view of entropy
• Shake, Rattle and Roll: Entropy changes can drive work.
• Shake, Rattle and Roll: Ethalpy vs. Entropy
• A Molecular View of Entropy: relating the molecular picture to work, heat and enthalpy
