Editing Adiabatic process (section)

==Etymology==
The term ''adiabatic'' ({{IPAc-en|ˌ|æ|d|i|ə|ˈ|b|æ|t|ɪ|k}}) is an anglicization of the [[Ancient Greek|Greek]] term ἀδιάβατος "impassable" (used by [[Xenophon]] of rivers). It is used in the thermodynamic sense by [[William John Macquorn Rankine|Rankine]] (1866),<ref name="Rankine 1866">[[William John Macquorn Rankine|Rankine, William John MacQuorn]] (1866). On the theory of explosive gas engines, ''The Engineer'', July 27, 1866; at page 467 of the reprint in ''[[iarchive:miscellaneoussci00rank|Miscellaneous Scientific Papers]]'', edited by W. J.

The etymological origin corresponds here to an impossibility of [[Heat|transfer of energy as heat]] and of transfer of matter across the wall.

The Greek word ἀδιάβατος is formed from [[privative a|privative ἀ-]] ("not") and διαβατός, "passable", in turn deriving from διά ("through"), and βαῖνειν ("to walk, go, come").<ref>[[Henry Liddell|Liddell, H. G.]], [[Robert Scott (philologist)|Scott, R.]] (1940). ''A Greek-English Lexicon'', Clarendon Press, Oxford, UK.</ref>

Furthermore, in [[atmospheric thermodynamics]], a diabatic process is one in which heat is exchanged.<ref>{{cite web|url=https://glossary.ametsoc.org/wiki/Diabatic_process|title=diabatic process|access-date=24 November 2020|publisher=American Meteorological Society}}</ref> An adiabatic process is the opposite – a process in which no heat is exchanged.
