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: 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.

Detailed explanation-3: -Endothermic Reactions A few examples of the endothermic process are photosynthesis, evaporating liquids, melting ice, dry ice, alkane cracking, thermal decomposition, ammonium chloride in water and much more.

Detailed explanation-4: -What is an Endothermic Reaction? Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products. These reactions lower the temperature of their surrounding area, thereby creating a cooling effect.

Detailed explanation-5: -There are two methods for distinguishing between exothermic and endothermic reactions. When energy is released in an exothermic reaction, the temperature of the reaction mixture increases. When energy is absorbed in an endothermic reaction, the temperature decreases.
