endothermic
This term functions as a technical descriptor in two distinct scientific domains. In chemistry, it describes a process that acts as a heat sink, drawing energy inward to break chemical bonds, which typically results in a cooling effect on the immediate surroundings.
In biology, the term refers to the physiological ability of an organism to generate its own heat internally. This distinguishes warm-blooded creatures from ectothermic organisms, which must rely on external heat sources to regulate their metabolic rates.
Meanings
Requiring or absorbing heat from the surrounding environment for a chemical reaction to occur.
The decomposition of calcium carbonate is an endothermic reaction.
Capable of maintaining a constant internal body temperature through metabolic processes regardless of the external environment.
Mammals and birds are endothermic animals that can survive in cold climates.
