For a process at constant volume,

Question

Quizplus · Accepted Answer

For a process at constant volume, no work is done as the volume remains constant. Therefore, the change in internal energy (ΔE) is equal to the heat (q) transferred into or out of the system. Thus, option B is the best choice as it states that there is no work done and ΔE is equal to q. The other options are incorrect as they imply a non-zero work done or relate ΔH to q, which is not applicable for a process at constant volume.
