If q = 39 kJ and w = -74 kJ for a certain process,it most likely _____.

Question

Quizplus · Accepted Answer

The given values of q and w indicate that the process is taking in heat (q is positive) and doing work on the system (w is negative). This means that the change in internal energy (ΔU) of the system is negative (ΔU = q + w), indicating an endothermic process. Thus, the best choice is B, which states that the process is endothermic. The other choices are not supported by the information given.
