Here are the solutions to the questions: 9. The expression U = q_v implies a condition under which According to the First Law of Thermodynamics, U = q + w. When a process occurs at constant volume ( V = 0), the pressure-volume work (w = -P V) is zero. Therefore, the change in internal energy ( U) is equal to the heat exchanged at constant volume (q_v). The term "heat absorbed" refers to a positive q. A. The heat absorbed by the system in the course of a reaction occurs at constant volume B. The heat absorbed by the surrounding occurs at constant volume in the course of a reaction
