An endotherm (from Greek ἔνδον endon "within" and θέρμη thermē "heat") is an organism that maintains its body at a metabolically favorable temperature, largely by the use of heat released by its internal bodily functions instead of relying almost purely on ambient heat. Such internally generated heat is mainly an incidental product of the animal's routine metabolism, but under conditions of excessive cold or low activity an endotherm might apply special mechanisms adap… Web1. An example of an exothermic reaction is: the lighting of a match an instant cold pack when two chemicals are added together evaporation of water the breaking of bonds 2. Enthalpy change is the...

Exothermic Definition & Meaning - Merriam-Webster
An ectotherm (from the Greek ἐκτός (ektós) "outside" and θερμός (thermós) "heat") is an organism in which internal physiological sources of heat are of relatively small or of quite negligible importance in controlling body temperature. Such organisms (for example frogs) rely on environmental heat sources, which permit them to operate at very economical metabolic rates. WebSep 12, 2024 · An exothermic reaction can lead to thermal runaway, which begins when the heat produced by the reaction exceeds the heat removed. The surplus heat raises … WebClassify each of the following as an exothermic or endothermic reaction. Part A A reaction releases 550 kJ.
