A presenter-led science video investigating exothermic and endothermic reactions, with Dr Maggie Aderin-Pocock and Dr Alex Lathbridge.

This video is about what exothermic and endothermic reactions are and how temperature changes can be used to identify which reaction is which. Exothermic reactions, in solution, give out energy ...

Heat packs that contain iron and water packets: Exposing the solution to air results in the oxidation of the iron (creates rust). The oxidation of the iron is an exothermic process. Heat packs that ...
