Short explanation
In the subtopic Energy transfer during exothermic and endothermic reactions, this learning objective focuses on define an exothermic reaction as one that transfers energy to the surroundings. It belongs to Exothermic and endothermic reactions in AQA GCSE Chemistry 8462 Unit 4.5 Energy changes, so the explanation must stay inside energy-transfer, reaction-profile, cell, fuel-cell, exothermic, endothermic, activation-energy or bond-energy context as appropriate. Approved keywords to use include exothermic reaction, surroundings. Surroundings. means the environment around a chemical reaction where energy transfer occurs Avoid the mistake of students often think that exothermic reactions absorb energy from the surroundings instead of transferring it; instead, remember that an exothermic reaction is defined as one that transfers energy to the surroundings, resulting in a release of heat For exam answers, define exothermic reactions clearly, focusing on their energy transfer to the surroundings
