An endothermic reaction is a chemical or physical process defined by its absorption of energy, typically heat, from its immediate environment. The term combines the Greek prefix “endo-,” meaning inward, with “thermic,” relating to heat.

An endothermic process is a chemical or physical process that absorbs heat from its surroundings. [1] In terms of thermodynamics, it is a thermodynamic process with an increase in the enthalpy H (or internal energy U) of the system. [2] In an endothermic process, the heat that a system absorbs is thermal energy transfer into the system.
Endothermic Process Examples An endothermic process is a more general term for a heat-absorbing phenomenon. Processes aren’t always easily written as chemical reactions, either because the reactants don’t change their chemical identity (as in phase changes), the chemistry is complex, or the nature of the reactants isn’t known.
Endothermic and exothermic reactions can be visually represented by energy-level diagrams like the ones in Figure 7 3 2. In endothermic reactions, the reactants have higher bond energy (stronger bonds) than the products.
Endothermic and exothermic reactions are the yin and yang of the chemical world. They reflect the fundamental truth that energy cannot be created or destroyed—only transformed.
Learn how to perform hot and cold chemistry experiments while learning about endothermic and exothermic chemical reactions.
Learn how exothermic and endothermic reactions work, why chemical bonds matter, and where these energy exchanges show up in everyday life and biology.
Learn the difference between endothermic and exothermic reactions and read about some practical examples of each type of reaction!
Energy diagrams for endothermic and exothermic reactions In the case of an endothermic reaction, the reactants are at a lower energy level compared to the products—as shown in the energy diagram below. In other words, the products are less stable than the reactants.
ENDOTHERMIC definition: noting or pertaining to a chemical change that is accompanied by an absorption of heat (opposed to exothermic). See examples of endothermic used in a sentence.
