endoergic

Thân thiện

A scientist observes an endoergic reaction in a laboratory chamber.

Definition

1. Adjective:
   • (Chemistry, Physics) Absorbing energy; requiring an input of energy to occur. This term is primarily used to describe a process, especially a nuclear or chemical reaction, that does not release energy into its surroundings but instead consumes it from the surroundings.

Usage

• As an adjective modifying a noun: The word "endoergic" directly describes a reaction or process.
  • An endoergic reaction cannot proceed spontaneously; it needs an external energy source.
  • The scientist studied the endoergic properties of the new compound.

Advanced Usage

• In technical contexts: The term is almost exclusively used in scientific fields like nuclear physics, chemistry, and thermodynamics to contrast with "exoergic" (energy-releasing) reactions.
  • The fusion of light nuclei at low temperatures is an endoergic process.

Variants and Related Words

• Endothermic (adj): A closely related term in chemistry, specifically referring to processes that absorb heat. While all endothermic processes are endoergic, not all endoergic processes are endothermic (e.g., some may absorb other forms of energy).
  • The melting of ice is an endothermic change.

Synonyms

• Energy-absorbing: A more general, descriptive synonym.
• Non-spontaneous: In thermodynamics, indicating a process that requires an external driving force.

Antonyms

• Exoergic (adj): Releasing energy.
  • Combustion is a classic exoergic reaction.
• Exothermic (adj): Releasing heat energy.
