In this video I work through real Cambridge IGCSE Chemistry (0620) past paper questions on exothermic and endothermic reactions, topic 5.1, step by step. We go through typical exam questions: identifying whether a reaction is exothermic or endothermic from temperature data, explaining energy transfer to and from the surroundings, interpreting and drawing energy level diagrams, and the exact wording examiners award marks for. I'll flag the common mistakes that lose easy marks and show you how to avoid them. New to this topic?
