Conservation and dissipation of energy
Question
- A. It is created anew
- B. It is stored for later use
- C. It is transferred to less useful stores
- D. It is destroyed completely
Answer
It is transferred to less useful stores
Explanation
The correct option is "It is transferred to less useful stores". It is transferred to less useful stores is right because it directly matches Efficiency: (HT only) Explain how reducing unwanted energy transfers improves efficiency.. The other options are less suitable because they change the required Physics relationship, confuse the relevant energy store or use a distractor that does not answer the question.
Common mistake
Misunderstanding Efficiency Improvement
Students often think that reducing unwanted energy transfers means eliminating all energy loss, which is impossible in real systems.
Clarify that while energy losses can be minimized, no system can be perfectly efficient due to inherent energy dissipation.
