(adiabatic)
21Adiabatic flame temperature — In the study of combustion, there are two types of adiabatic flame temperature depending on how the process is completed: constant volume and constant pressure. The constant volume adiabatic flame temperature is the temperature that results from… …
22Adiabatic theorem — The adiabatic theorem is an important concept in quantum mechanics. Its original form, due to Max Born and Vladimir Fock (1928),cite journal |author=M. Born and V. A. Fock |title=Beweis des Adiabatensatzes |journal=Zeitschrift für Physik A… …
23adiabatic lapse rate — The rate at which the temperature changes as the air rises or falls without the heat being taken away from or given to the air mass. The standard adiabatic lapse rate is 3°C/1000 ft, 5.4°F/1000 ft, or 9.8°C/km when air is dry (dry adiabatic lapse …
24adiabatic process — ▪ physics in thermodynamics, change occurring within a system as a result of transfer of energy to or from the system in the form of work only. A rapid expansion or contraction of a gas is very nearly adiabatic. Any process that occurs… …
25adiabatic chart — noun : a meteorological chart with coordinates usually given as pressure and temperature on which adiabats have been superposed to assist in evaluating adiabatic energy transformations in the atmosphere * * * a graph for the analysis of adiabatic …
26adiabatic gradient — noun : the rate at which the temperature of an ascending or descending body of air is changed by adiabatic expansion or compression, being about 1.6° F. for each 300 feet of change of height; also : a curve representing this * * * adiabatic… …
27adiabatic chart — a graph for the analysis of adiabatic processes. Also called adiabatic diagram. * * * …
28adiabatic demagnetization — ▪ physics process by which the removal of a magnetic field from certain materials serves to lower their temperature. This procedure, proposed by chemists Peter Debye (Debye, Peter) (1926) and William Francis Giauque (Giauque, William… …
29adiabatic shear band — an adiabatic shear band is a narrow region, usually a few microns (micrometers) wide of intense plastic deformation that forms in high strain rate deformations of most metals, some polymers and several other material. Because of very little time… …
30adiabatic process — /ˌædiəbætɪk ˈproʊsɛs/ (say .adeeuhbatik prohses) noun Thermodynamics the thermodynamic transformation which occurs in a system without the exchange of heat between the system and its environment, as in the adiabatic cooling of a parcel of air… …
