Endothermic reactions: Heat is absorbed. 1) Photosynthesis: Plants absorb heat energy from sunlight to convert carbon dioxide and water into glucose and oxygen. 2) Cooking an egg: Heat energy is absorbed from the pan to cook the egg. Exothermic reactions: Heat is released.
Chemical energy Chemical Energy is released when bonds form in a chemical reaction, often producing heat as a by-product (exothermic reaction). There are two important terms to know in the study of chemical energy. 1. Exoergic: An exothermic (exoergic) nuclear reaction is a reaction that releases energy when chemical bonds form. 2. Endoergic: an endothermic (or endoergic) reaction is one that requires an input of energy to take place.
