Endothermic reactions are the opposite. The new bonds require more energy. This comes from heating the substances, or sometimes, comes from the surrounding environment. Absorbing heat energy from the environment makes everything decrease in temperature so the reaction 'feels' cooler.
Thus in each term the prefix refers to where heat goes as the reaction occurs. The term endothermic was coined by Marcellin Berthelot. The concept is frequently applied in physical sciences to, for example, chemical reactions, where thermal energy is converted to chemical bond energy.ndothermic. In thermodynamics, the word endothermic describes a process or reaction in which the system absorbs energy from its surroundings in the form of heat. It is a modern coinage from Greek roots.
