A) It ends up as chemical energy that performs useful work.
B) It ends up as low-quality heat energy that flows into the environment.
C) It ends up as electrical energy that performs useful work.
D) It ends up as mechanical energy that performs useful work.

Question

Robert Vasquez · Accepted Answer

Final Answer : B, Explanation :  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.
