Quizplus · Accepted Answer

The second law of thermodynamics states that energy cannot be converted without some loss of usable energy in the process, usually to low-quality heat energy that flows into the environment. Therefore, choice B is the correct answer as it shows what typically happens to energy during an energy transformation.
