Problem 3.1:
Suppose we have N systems prepared, and the first is in thermal
equilibrium with the second, the second in thermal equilibrium with the
third, etc., until system N - 1 is in thermal equilibrium with the
Nth system. Is the first system in thermal equilibrium with the
Nth?
[Solution]
Problem 3.2:
Does the Third Law insist that the entropy go to zero as the temperature
approaches zero?
[Solution]
Problem 3.3:
Is this statement true? Why or why not?: As the temperature approaches
0oC, the entropy approaches a constant value.
[Solution]
Problem 3.4:
Is this statement true? Why or why not: every system will increase in entropy
as time passes.
[Solution]
Problem 3.5:
In the jargon of the Second Law, what does it mean for a process to be
path independent?
[Solution]
