GENERAL KNOWLEDGE

Detailed explanation-1: -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-2: -Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products.

Detailed explanation-3: -The reaction in which energy is absorbed is called an endothermic reaction. The term endothermic process describes a process or a reaction in which the system absorbs energy from its surroundings usually in the form of heat.

Detailed explanation-4: -Complete answer:-Those reactions in which the reaction absorbs heat energy (thermal energy) from its surroundings and forms products are known as endothermic reactions. When these reactions absorb heat from outside sources they lower the temperature of the surroundings and thus cause a cooling effect.
