Etymology
19th-century coinage (introduced by W. J. M. Rankine in the 1860s) based on Ancient Greek ἀδιάβατος (adiábatos, “impassable”), used of terrain (rivers, forests) by Xenophon, from ἀ- (a-, “not”) + διά (diá, “through”) + βατός (batós, “passable”), from βαίνω (baínō, “to go”).
Meanings
-
(not-comparable, of a process) Without gain or loss of heat (and thus with no change in entropy, in the quasistatic approximation).
New 2.4 GWh adiabatic compressed air energy storage (CAES) plant now operational in in ^([sic]) Jiangsu province.
2026 January 27, Lynas, Matthew, “World’s largest compressed-air storage plant switched on in China”, in pv magazine:Talk of dynamic compression and adiabatic gradients didn't carry as much weight as the certainty of its conscious intent.
2006, Thomas Pynchon, Against the Day, Vintage 2007, page 737:The line drawn on the indicator diagram in the latter case has been named by Professor Rankine an Adiabatic line, because it is defined by the condition that heat is not allowed to pass through (διαβαίνειν) the vessel which confines the substance.
1871, James Clerk Maxwell, Theory of Heat, page 129:
-
(not-comparable, of a process, qualifier:quantum mechanics) Involving the slow change of the Hamiltonian of a system from its initial value to a final value.
In this section we examine the limiting cases when T is very small (sudden change) and very large (adiabatic change).
1961, Albert Messiah, Quantum Mechanics, volume II, page 740:
