Question

State the fundamental assumption of statistical mechanics and fully explain its implications for large interacting subsystems isolated from their environment.

Some statements of the second law of thermodynamics read simply that “Entropy never decreases.” Is this really the case? Explain fully.

Answer 1

The Statistical fundamental mechanics of assumption says, that at equillibrium, the probability of finding the system من one that particulas aci eyible state is same any othes Fol large interacting subsystems isolated from environment, since the probability of finding the particles can be found out and inside the system the probability of finding the particle is 100 percent from second law of thermodynamiy, the total entropy of universe never decreases Actually entropy can decrease, but at the same time, some where it increases. There fore the net rate of the entire system always decreases
