Noun

exergy (countable and uncountable, plural exergies)

1. (physics) Concentrated or organized energy, which can be exported and do work in the process.

     The maximum fraction of an energy form which (in a reversible process) can be transformed into work is called exergy. The remaining part is called anergy, and this corresponds to the waste heat.
