adiabatic

[ ad-ee-uh-bat-ik, ey-dahy-uh- ]

adjective

1. occurring without gain or loss of heat ( diabatic ):

   an adiabatic process.

adiabatic

/ ˌeɪ-; ˌædɪəˈbætɪk /

adjective

1. (of a thermodynamic process) taking place without loss or gain of heat

noun

1. a curve or surface on a graph representing the changes in two or more characteristics (such as pressure and volume) of a system undergoing an adiabatic process

adiabatic

/ ăd′ē-ə-băt′ĭk /

1. Occurring without gain or loss of heat. When a gas is compressed under adiabatic conditions, its pressure increases and its temperature rises without the gain or loss of any heat. Conversely, when a gas expands under adiabatic conditions, its pressure and temperature both decrease without the gain or loss of heat. The adiabatic cooling of air as it rises in the atmosphere is the main cause of cloud formation.

Word History and Origins

Origin of adiabatic¹

1875–80; < Greek adiábat ( os ) incapable of being crossed ( a- a- ⁶ + dia- dia- + ba- (stem of baínein to cross) + -tos verbal adjective suffix) + -ic; diabatic

Word History and Origins

Origin of adiabatic¹

C19: from Greek adiabatos not to be crossed, impassable (to heat), from a- ¹+ diabatos passable, from dia- across + bainein to go

Example Sentences

However, when COPs involve constraints, conventional quantum algorithms like adiabatic quantum annealing struggle to obtain a near-optimal solution within the operation time of quantum computers.

From Science Daily

In contrast, adiabatic evolution can always keep the quantum system in its eigenstate.

From Science Daily

There will also be some downsloping, or air cascading from higher elevations to lower, which results in “adiabatic compression” — as air descends, it heats up and dries out.

From Washington Post

The catch is that, to avoid transferring any heat—that is, to be what physicists call an adiabatic process—the series of logical operations in the computation must usually be carried out infinitely slowly.

From Scientific American

Microsoft’s data centers currently use adiabatic cooling, which relies on outside air to cool down temperatures inside.
