Problems

Problem :

Take a system with a multiplicity function such that g(N, U) = 100 . What is the entropy of the system, and in what units?


Problem :

What is the conventional entropy S of the system in the above problem?


Problem :

Say that we had a system in which adding a small bit of energy actually decreased the entropy. What can you say about the temperature of the system?


Problem :

Say that in a large system, adding one Joule of energy increases the entropy by 1020 . What is the approximate temperature of the system?


Problem :

What is the temperature in kelvin of the system in the previous problem?
