Endothermic reaction (Endothermic reaction) is a chemical reaction that absorbs energy to break a bond, rather than spit it out to create a bond. This reaction absorbs heat in the precursor is low than the products, thus making the environment cooler temperature decreased. When removing the hand touching the utensils will feel cold.The reaction heat (Exothermic reaction) to evolve into a reaction that absorbs energy to break a bond less than spit out in order to create a bond. In this reaction give off heat energy is precursor to higher product, designed to heat the environment. Make the high temperature. When removing the hand touching the utensils will feel hot.
