# Adiabatic compression of the gas.

* Adiabatic storage retains the heat produced by compression and returns it to the air when the air is expanded to generate power.

* Adiabatic compression heating in the trough of each wave oscillation may also evaporate cumulus or stratus clouds in the airmass, creating a " wave window " or " Foehn gap ".

" Adiabatic free expansion.

# Adiabatic expansion of the gas.

Adiabatic expansion causes the aerosol contents to cool rapidly on exiting the can.

Adiabatic heating occurs when the pressure of a gas is increased from work done on it by its surroundings, e. g. a piston.

Adiabatic heating also occurs in the Earth's atmosphere when an air mass descends, for example, in a katabatic wind or Foehn or chinook wind flowing downhill over a mountain range.

Adiabatic cooling occurs when the pressure of a substance is decreased as it does work on its surroundings.

Adiabatic processes can occur if the container of the system has thermally-insulated walls or the process happens in an extremely short time, so that there is no opportunity for significant heat exchange.

Adiabatic changes in temperature occur due to changes in pressure of a gas while not adding or subtracting any heat.

Adiabatic cooling occurs in the Earth's atmosphere with orographic lifting and lee waves, and this can form pileus or lenticular clouds if the air is cooled below the dew point.

Adiabatic cooling does not have to involve a fluid.

Lockheed Martin and the University of Southern California ( USC ) reached an agreement to house the D-Wave One Adiabatic Quantum Computer at the newly formed USC Lockheed Martin Quantum Computing Center, part of USC's Information Sciences Institute campus in Marina del Rey.

* Adiabatic magnetization: A magnetocaloric substance is placed in an insulated environment.

* Adiabatic demagnetization: The substance is returned to another adiabatic ( insulated ) condition so the total entropy remains constant.

Reversible Adiabatic Process | adiabatic process: The state on the left can be reached from the state on the right as well as vice versa without exchanging heat with the environment.

( Adiabatic effects in rapidly expanding compressed gases can generate very high temperatures, up to 1000 degrees Celsius.

This occurs because internal combustion engines are heat engines, and higher efficiency is created because higher compression ratios permit the same combustion temperature to be reached with less fuel, while giving a longer expansion cycle, creating more mechanical power output and lowering the exhaust temperature.

The engine converts the working fluid from a gas to a liquid, from liquid to gas, or both, generating work from the fluid expansion or compression.

Gas turbine cycle engines employ a continuous combustion system where compression, combustion, and expansion occur simultaneously at different places in the engine — giving continuous power.

Internal stresses from this expansion generally take the form of compression on the crystals of martensite and tension on the remaining ferrite, with a fair amount of shear on both constituents.

Pressure waves or Primary waves ( P-waves ), are longitudinal waves that involve compression and rarefaction ( expansion ) in the direction that the wave is traveling.

Stretching of a rubber band is in some ways equivalent to the compression of an ideal gas, and relaxation is equivalent to its expansion.

Companding can also refer to the use of compression, where gain is decreased when levels rise above a certain threshold, and its complement, expansion, where gain is increased when levels drop below a certain threshold.

The phase vocoder handles sinusoid components well, but early implementations introduced considerable smearing on transient (" beat ") waveforms at all non-integer compression / expansion rates, which renders the results phasey and diffuse.

Recent improvements allow better quality results at all compression / expansion ratios but a residual smearing effect still remains.

These are isentropic compression, isobaric ( constant pressure ) combustion and isentropic expansion.

Thus a cycle of expansion and compression ( swelling and shrinking ) is maintained.

A gamma value is sometimes called an encoding gamma, and the process of encoding with this compressive power-law nonlinearity is called gamma compression ; conversely a gamma value is called a decoding gamma and the application of the expansive power-law nonlinearity is called gamma expansion.

Output to CRT-based television receivers and monitors does not usually require further gamma correction, since the standard video signals that are transmitted or stored in image files incorporate gamma compression that provides a pleasant image after the gamma expansion of the CRT ( it is not the exact inverse ).

* Dynamic range compression during recording and expansion during playback expanded the available dynamic range and improved the signal-to-noise ratio.

Compressive asphyxia ( also called chest compression ) is mechanically limiting expansion of the lungs by compressing the torso, hence interfering with breathing.

Other weapons use the compression or expansion of gases as their motive force.

The Otto cycle consists of adiabatic compression, heat addition at constant volume, adiabatic expansion, and rejection of heat at constant volume.

In the case of a four-stroke Otto cycle, technically there are two additional processes: one for the exhaust of waste heat and combustion products ( by isobaric compression ), and one for the intake of cool oxygen-rich air ( by isobaric expansion ); however, these are often omitted in a simplified analysis.

Processes 1-2 and 3-4 do work on the system but no heat transfer occurs during adiabatic expansion and compression.

Dolby B uses volume compression and expansion of high frequencies to boost low-level treble information by up to 9 dB, reducing them ( and the hiss ) on playback.

The expansion cylinder ( red ) is maintained at a high temperature while the compression cylinder ( blue ) is cooled.

A Stirling engine is a heat engine operating by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work.
