Solve and submit Baierlein 5.1, 5.2, 5.4 (see note below), 5.5

Note for 5.4: the 'magnetization' is the magnetic moment per unit volume for a collection of many moments. In this problem there is only one moment and hence the problem should more appropriately refer to the 'magnetization per particle (or per atom)'.

Homework #5 (Updated)

Homework #5, due in class on Friday Oct. 23:

Solve and submit from Baierlein: 3.10, 3.11, 3.12 (see note below), 3.13, two extra problems attached.

Solve for yourself B3.9

Note in regard to 3.12: the question is asking about the maximum amount of work by any engine working in the configuration described. To simplify your solution you can assume that at the stage during which Qhot is transferred to the engine, there is no change in the temperature of the hot reservoir (and that the change in the hot reservoir occurs after that stage is done).

Statistics for HW5
Average = 67; standard deviation = 21; max = 100; min = 27
