Detailed explanation-1: -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-2: -An endothermic process absorbs heat and cools the surroundings.”

Detailed explanation-3: -In the course of an exothermic reaction, heat flows from the system to its surroundings, and thus, gets warm. Heat is absorbed by reactants to form products.

Detailed explanation-4: -In exothermic reactions heat is given out so the enthalpy of products is less than the enthalpy of the reactants and the enthalpy change is negative. In endothermic reactions, heat is absorbed this increases the enthalpy of the products in such a case enthalpy change of the reaction is positive.

Detailed explanation-5: -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.
