  2. Endothermic process - Wikipedia

    en.wikipedia.org/wiki/Endothermic_process

    Thus, an endothermic reaction generally leads to an increase in the temperature of the system and a decrease in that of the surroundings. [1] The term was coined by 19th-century French chemist Marcellin Berthelot. [3] The term endothermic comes from the Greek ἔνδον (endon) meaning 'within' and θερμ- (therm) meaning 'hot' or 'warm'. [4]

  3. Endotherm - Wikipedia

    en.wikipedia.org/wiki/Endotherm

    Endothermic animals mostly use internal heat production through metabolic active organs and tissues (liver, kidney, heart, brain, muscle) or specialized heat producing tissues like brown adipose tissue (BAT). In general, endotherms therefore have higher metabolic rates than ectotherms at a given body mass.

  4. Thermal decomposition - Wikipedia

    en.wikipedia.org/wiki/Thermal_decomposition

    The reaction is usually endothermic as heat is required to break chemical bonds in the compound undergoing decomposition. If decomposition is sufficiently exothermic, a positive feedback loop is created producing thermal runaway and possibly an explosion or other chemical reaction. Thermal decomposition is a chemical reaction where heat is a ...

  5. Thermochemistry - Wikipedia

    en.wikipedia.org/wiki/Thermochemistry

    Thermochemistry is useful in predicting reactant and product quantities throughout the course of a given reaction. In combination with entropy determinations, it is also used to predict whether a reaction is spontaneous or non-spontaneous, favorable or unfavorable. Endothermic reactions absorb heat, while exothermic reactions release heat ...

  6. Chemical reaction - Wikipedia

    en.wikipedia.org/wiki/Chemical_reaction

    Reactions can be exothermic, where ΔH is negative and energy is released. Typical examples of exothermic reactions are combustion, precipitation and crystallization, in which ordered solids are formed from disordered gaseous or liquid phases. In contrast, in endothermic reactions, heat is consumed from the environment. This can occur by ...

  7. Exothermic process - Wikipedia

    en.wikipedia.org/wiki/Exothermic_process

    Chemical exothermic reactions are generally more spontaneous than their counterparts, endothermic reactions. [16] In a thermochemical reaction that is exothermic, the heat may be listed among the products of the reaction.

  9. Nuclear reaction - Wikipedia

    en.wikipedia.org/wiki/Nuclear_reaction

    Kinetic energy may be released during the course of a reaction (exothermic reaction) or kinetic energy may have to be supplied for the reaction to take place (endothermic reaction). This can be calculated by reference to a table of very accurate particle rest masses, [4] as follows: according to the reference tables, the 6 3 Li
