Question

Quizplus · Accepted Answer

In option B, the system gains energy but work is performed on it, which means that some of the energy is converted into internal energy, resulting in an overall increase in the internal energy of the system. Option A could potentially increase or decrease the internal energy, depending on how much energy is lost through work. Options C and D involve the loss of energy, so they would not always increase the internal energy. Option E is incorrect, as option B will always increase the internal energy.
