Adiabatic (from Gr. ἀ negative + διάβασις passage; transference) refers to any process that occurs without heat transfer. This concept is used in many areas of physics and engineering. Notable examples are listed below.

Automobiles

• Engine braking, a feature of some diesel engines, uses adiabatic expansion to diminish the vehicle's forward momentum.

Meteorology

• Adiabatic lapse rate, the change in air temperature with changing height, resulting from pressure change.

Quantum chemistry

• Adiabatic invariant Born–Oppenheimer approximation

Thermodynamics

• Adiabatic process

• Adiabatic ionization

• Adiabatic index

• Adiabatic accessibility

Quantum mechanics

• Adiabatic theorem

• Adiabatic quantum motor

Electronics

• Adiabatic circuit

• Adiabatic logic
