exoergic

Thân thiện

A nuclear fusion reaction in a star is an exoergic process.

Definition

1. Adjective:
   • (Of a nuclear reaction) occurring with the release of energy: Describes a process, typically a nuclear or chemical reaction, where energy (often in the form of heat or radiation) is released into the surroundings. The system loses energy.

Usage

• The term is primarily used in scientific contexts, especially in physics, chemistry, and nuclear engineering, to describe energy-releasing processes.
• It is the opposite of endoergic (or endothermic for chemical reactions), which describes a process that absorbs energy.

Examples

• Adjective:
  • The fusion of hydrogen atoms in the sun is an exoergic process that provides Earth with light and heat.
  • Scientists are researching controlled exoergic nuclear reactions for potential power generation.

Advanced Usage

• In broader contexts: While most precise in nuclear physics, "exoergic" can sometimes be used more loosely to describe any spontaneous process that releases energy.
  • The exoergic nature of the compound's decomposition makes it useful in certain propellants.

Variants and Related Words

• Exothermic (adj): The more common term used specifically for chemical reactions that release heat energy.
  • The combustion of fuel is an exothermic reaction.
• Exergonic (adj): A term used in thermodynamics for processes that release energy, often encompassing non-heat forms like light or electrical energy.

Synonyms

• Energy-releasing
• Exothermic (for heat-releasing chemical reactions)

Antonyms

• Endoergic (adj): (Of a nuclear reaction) occurring with absorption of energy.
• Endothermic (adj): (Of a chemical reaction) accompanied by absorption of heat.
