# Problem: The contents of the closed box in each of the following illustrations represent a system, and the arrows show the changes to the system during some process. The lengths of the arrows represent the relative magnitudes of q and w. (a) Which of these processes is endothermic?

🤓 Based on our data, we think this question is relevant for Professor Geissler's class at CAL.
