Detailed explanation-1: -An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.”
Detailed explanation-2: -Detailed Solution The correct answer is Respiration. Respiration is an exothermic process. A process is exothermic when there is the heat evolved in the reaction. Examples of exothermic reaction: Combustion, Detonation of Nitroglycerin, Nuclear Fission of Uranium-235, Neutralization Reactions, respiration, etc.
Detailed explanation-3: -Chemical reactions that release energy are called exothermic. In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants. Chemical reactions that absorb (or use) energy are called endothermic.
