Calorimetry is the science or act of calculating changes in a body's state variables in order to extract the heat transfer associated with changes in its condition attributable, for example, to chemical reactions, physical changes, or phase transitions under defined constraints. Calorimetry calculates the heat produced by living organisms by measuring either their production of carbon dioxide and nitrogen waste (often ammonia in aquatic or terrestrial organisms) or their consumption of oxygen.
