For ΔE_systo always be -,what must be TRUE? A) q = w B) +q > -w C) +w > -q D) -w > +q

Quizplus · Accepted Answer

The equation ΔE = q - w states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system. In order for ΔE_systo always be negative, we need w to be greater than q. Therefore, -w must be greater than +q, which is expressed in choice D.
