Question

In which of the following scenarios is no change in the internal energy of the system possible? A)q < 0,w > 0 B)q > 0,w > 0 C)q = 0,w > 0 D)q < 0,w = 0 E)q < 0,w < 0

Quizplus · Accepted Answer

According to the first law of thermodynamics, the change in internal energy (ΔU) is given by ΔU = q + w. In scenario A, the heat lost by the system (q < 0) is exactly balanced by the work done on the system (w > 0), resulting in no change in internal energy (ΔU = 0).
