In a combustion reaction, fuel is burned and reacts with oxygen to release energy. Respiration is the chemical change that takes place inside living cells. Glucose and oxygen are used to release ...

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 ...

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 ...
