Question

Why are the signs for endothermic and exothermic reactions switched between chemistry and physics? It's pretty confusing.
Please explain in your own words and do not answer with random stuff or 'I don't know'
Thanks

Answer 1

In a chemical equation, the location of the word "heat" can be used to quickly determine whether the reaction is endothermic or exothermic. If heat is released as a product of the reaction, the reaction is exothermic. If heat is listed on the side of the reactants, the reaction is endothermic.
