Exothermic process - Wikipedia
WebExothermic reactions transfer energy to the surroundings and the temperature of the surroundings increases. Endothermic reactions take in energy and the temperature of the surroundings decreases. WebExothermic and endothermic describe two types of chemical reactions or systems found in nature, as follows: Exothermic [ edit ] After an exothermic reaction , more energy has been released to the surroundings than was absorbed to initiate and maintain the reaction. thameslink website
