Winter Semester
Week
 Problem
 Pedagogical goal
week 1 (25 October 2006)
 1.5 and 2.4
 Use partial derivatives. Work for a constant external pressure process.
week 2 (1er November)
 2.3 and 3.4
 Evaluate work for various processes. 
week 3 (8 November)
 3.1
Evaluate work for a constant external pressure process under various conditions.
week 4 (15 November)
 4.4 et 4.2
 Joule experiment. Compute entropy change for a reversible process and an irréversible one.  
week 5 (22 November)
 4.5 and 3.3  Stress that an entropy change for an irreversible process can be computed via any reversible change betweeen the same states.  Porblem 3.3 shows how a real process can approach a reversible one. 
week 6 (29 November)
