For all irreversible processes involving a system and its environment:
A)the entropy of the system does not change
B)the entropy of the system increases
C)the total entropy of the system and its environment does not change
D)the total entropy of the system and its environment increases
E)none of the above

Question

Quizplus · Accepted Answer

Irreversible processes always lead to an increase in the total entropy of the system and its environment, according to the second law of thermodynamics. This is because irreversibility leads to dissipation of energy, and the total entropy is a measure of the energy that is no longer available to do work. Therefore, the best choice is D.
