One of the mysteries of the English language finally explained.
1Relating to or denoting a process or condition in which heat does not enter or leave the system concerned.‘the adiabatic expansion of a perfect gas’
- ‘The quantum and classical Carnot engines therefore operate in the same way - a closed cycle of two isothermal and two adiabatic processes.’
- ‘My genetic code has been perfected by an intricate adiabatic process over ten decades, and I am practically immortal.’
- ‘Entropy, according to the 2nd law, can indeed remain constant but only either in reversible adiabatic processes or in reversible cycles.’
- ‘This is what makes the air cooler higher up: the process is called adiabatic expansion/compression.’
- ‘Working closely with environmental engineers, Arup New York, it settled on a passive climate controlled system known as adiabatic cooling, which takes advantage of the hot arid climate.’
- 1.1 Impassable to heat.
A curve or formula representing adiabatic phenomena.
- ‘On the thermal plane, the adiabatics appear as straight lines corresponding to different entropies.’
Late 19th century: from Greek adiabatos ‘impassable’, from a- ‘not’ + dia ‘through’ + batos ‘passable’ (from bainein ‘go’), + -ic.
