The following diagrams illustrate the flow of energy (q) and work (w) in different processes. Which one is definitely an exothermic process?

Question

Quizplus · Accepted Answer

In option C, the q value is negative, indicating that heat energy is being released from the system. This is characteristic of an exothermic process. In contrast, all other options have a positive q value, indicating that heat energy is being absorbed by the system, making them endothermic processes.
