the process by which the body produces water on the skin as a cooling strategy. It works because water absorbs energy when it changes state from a liquid to a gas. This is an endothermic process, but it isn't a reaction, because a reaction always involves the destruction or formation of ...
What is an endothermic reaction?Reactions:In science, there are all kinds of reactions and each reaction involves the exchange of something. Chemical reactions, for example, exchange molecules to either help separate or make new compounds.Answer and Explanation: ...

When a nucleus undergoes transmutation – either by splitting, or fusing, or by gaining or losing nucleons – the total binding energy held in the nuclear bonds changes. Depending on the type of reaction, nuclear energy is either released (exothermic reaction) or consumed (endothermic reaction)....
As the reaction progresses, it can either generate heat, increasing the temperature in its surroundings (exothermic reaction), or absorb heat (endothermic). The heat can be easily measured using the following equation: q = mwaterx Cwaterx (Tf-T0) ...
