This is shown by larger energy arrows coming out of the products and smaller energy arrows going into the reactants. In this reaction, the temperature goes down, so it is endothermic. In an ...

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 ...

Not all reactions give off heat like this. In fact, some actually take in or absorb energy from their surroundings, and the reacting substances feel cold. They’re called endothermic reactions.
