For ?E sys to always be -,what must be true?

Question

Quizplus · Accepted Answer

ΔES1U1B1sys is the change in internal energy of the system from state S1U1B0 to state S1U1B1. The sign of this change depends on the values of q and w (heat and work). If ΔES1U1B1sys is always negative, that means the internal energy of the system is decreasing in every process. In order for this to happen, the work done by the system must be greater than the heat absorbed by the system, i.e., -w > +q. Therefore, the correct answer is D.
