(Physics only) Explain that an object's temperature depends on the balance between radiation absorbed and radiation emitted.

(Physics only) Explain that an object's temperature depends on the balance between radiation absorbed and radiation emitted.. Within Electromagnetic waves, this learning objective sits inside Black body radiation (physics only) for AQA Physics 8463. Focus on using ideas such as physics only, temperature accurately in your explanation. A strong response should define the core idea, describe the relevant physical process, and connect it back to the question wording instead of giving a vague definition. When revising, students should aim to explain the subject clearly, include precise physics vocabulary, and show how the idea links to the wider topic rather than listing isolated facts.
