Explanation:
Detailed explanation-1: -Chemical reactions that absorb (or use) energy overall are called endothermic. In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products.
Detailed explanation-2: -Endothermic reactions absorb energy from the surroundings. This energy is usually absorbed as heat, so the surroundings get colder.
Detailed explanation-3: -An endothermic reaction is any chemical reaction that absorbs heat from its environment. The absorbed energy provides the activation energy for the reaction to occur. A hallmark of this type of reaction is that it feels cold.
Detailed explanation-4: -If
