Question
- A. It is created from nothing.
- B. It is transformed into different forms.
- C. It is lost to the environment.
- D. It is stored indefinitely.
Answer
The correct option is It is transformed into different forms.. This answer is correct because it matches the approved learning objective to apply conservation of energy to explain that energy cannot be created or destroyed during a chemical reaction in the subtopic Universal chemistry ideas.
Explanation
The correct option is It is transformed into different forms.. It is transformed into different forms. is correct because it directly supports the approved learning objective to apply conservation of energy to explain that energy cannot be created or destroyed during a chemical reaction. This belongs to the subtopic Universal chemistry ideas within Key ideas in chemistry, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Universal chemistry ideas.
Common mistake
Misunderstanding Energy Conservation
Students often think that energy can be created or destroyed during a chemical reaction.
Emphasize that energy is conserved in chemical reactions, meaning it can only change forms but cannot be created or destroyed.
