What does the term endothermic refer to?

Answer: The word endothermic describes a process or reaction in which the system absorbs energy from its surroundings in the form of heat.

Explanation:

Opposed to exothermic (the process in which a chemical change that is accompanied by a liberation of heat occurs), an endothermic process absorbs energy from its surroundings in the form of heat.

The definition of endothermic is a chemical reaction that is accompanied by the absorption of heat, or an organism that generates heat to maintain its temperature. A chemical reaction that works only if heat is absorbed is an example of a reaction that would be described as endothermic.
