HW8, problem 42

A slight correction to the problem statement:

In part (b), please calculate the entropy change for the world, i.e., that due to both the system and environment entropy change. The point is to show you that supercooled water freezes, the entropy of the world increases and thus this process does not violate the second law, even though "disorder" may seem to be decreasing.

Cheers,
