Question
- A. endothermic reaction: correct Unit 4.5 answer for Energy transfer during exothermic and endothermic reactions
- B. Incorrect: confuses endothermic reaction with a nearby Energy changes idea
- C. Incorrect: gives a general chemistry statement without linking to Energy transfer during exothermic and endothermic reactions
- D. Incorrect: reverses the energy-change relationship in Exothermic and endothermic reactions
Answer
The correct option is endothermic reaction: correct Unit 4.5 answer for Energy transfer during exothermic and endothermic reactions.
Explanation
The correct option is endothermic reaction: correct Unit 4.5 answer for Energy transfer during exothermic and endothermic reactions. It directly supports the approved learning objective to describe sports injury packs as an everyday use of endothermic reactions. This keeps the answer anchored to Energy transfer during exothermic and endothermic reactions within Exothermic and endothermic reactions, and avoids mixing energy transfer, reaction profiles, activation energy, chemical cells, fuel cells, exothermic reactions and endothermic reactions unless the objective names them.
Common mistake
Misidentifying the temperature change in sports injury packs
Students think sports injury packs warm the surroundings because they feel hot
Explain that sports injury packs are endothermic; they absorb heat from the surroundings, so the pack feels cold and the surrounding temperature falls
