In thermodynamics, the term exothermic process (exo- : outside) describes a 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), electricity (e.g. a battery), or sound (e.g. explosion heard when burning hydrogen).
The energy released in a nuclear reaction can appear mainly in one of three ways: ... that does not mean that the reaction really occurs. Read more. Positive: 95 %. Nuclear energy is released when an unstable nucleus is ... to heat a plasma of Deuterium and Tritium and produce nuclear energy from this fusion reaction.
