This topic explores the difference between endothermic and exothermic reactions in chemistry. Chemical reactions encompass a variety of processes categorised into subgroups, including endothermic and ...

Speaker one Have you ever had a bump or a sprain and needed a cold compress? Speaker two Yes, all the time. Now, some cold packs use a chemical reaction to absorb heat. This is an example of something ...

In this video, I explain why some reactions explode while others cool, exploring the root cause of chemical energy. I discuss the chemistry behind endothermic and exothermic reactions, which involves ...

Commercial heat packs (containing iron and water, or supersaturated sodium acetate) and cold packs (various ammonium salts) can be used to show exo- and endothermicity. Heat packs that contain iron ...
