In thermodynamics, an exothermic process (from Greek έξω (exō) 'outwards', and θερμικός (thermikόs) 'thermal' ) is a thermodynamic process or reaction that releases energy from the system to its surroundings, usually in the form of heat, but also in a form of light (e.g. a spark, flame, or flash), … See more Exothermic and endothermic describe two types of chemical reactions or systems found in nature, as follows: Exothermic After an exothermic reaction, more energy has been released … See more Some examples of exothermic processes are: • Combustion of fuels such as wood, coal and oil/petroleum • The thermite reaction • The reaction of alkali metals and other highly electropositive metals with water See more • Calorimetry • Chemical thermodynamics • Differential scanning calorimetry See more Exothermic refers to a transformation in which a closed system releases energy (heat) to the surroundings, expressed by $${\displaystyle Q>0.}$$ When the … See more Chemical exothermic reactions are generally more spontaneous than their counterparts, endothermic reactions. In a thermochemical reaction that is exothermic, the heat may be listed among the products of the reaction. See more • http://chemistry.about.com/b/a/184556.htm Observe exothermic reactions in a simple experiment See more Web2 days ago · Exothermic Reactions is the flow of the net transfer of heat energy during the reaction is from the medium into its surroundings. In exothermic reactions, the reactants always possess more energy than the products and hence are less stable. For this reason, the exothermic reactions require very less amount of activation energy to initiate the …
