Not giving out or receiving heat.
Of or denoting change in volume or pressure, with no heat gain or loss with the surrounding air.
(adj.) A process where no heat enters or leaves the system. In the atmospherie, when air rises, it expands because of a reduction in pressure. In the absence of non-adiabatic processes (condensation, evaporation, radiation), expansion causes the air to cool at about 1 degree per 300 feet.
A process in which there is no heat transfer, thus its temperature-entropy graph is a vertical straight line, and thus entropy is constant during the process.
A term indicating that no heat is lost or gained by a material being subjected to a thermodynamic process. An adiabatic process is one in which there is no exchange of heat with the surroundings.
Insulated and neither heated or cooled: as in an adiabatic change, where in a condition is altered without gain or loss of heat.
without the exchange of heat with the external universe.
A process condition in which there is not gain or loss of heat from the environment.
Occurring without loss or gain of heat. i.e., "adiabatic expansion of a body of air."
A change in gas condition where no heat is added or removed except in the form of work.
Involving or allowing neither gain nor loss of heat.
A chemical or mechanical process which takes place without heat entering or leaving the system. The term is only applicable to enclosed and isolated systems - so in essence is idealistic and purely theoretical and is important in the study of thermodynamics.
A body is said to undergo an adiabatic change when its condition is altered without gain or loss of heat.
this is a way to conduct a process. Other ways are isothermal or isobaric and so on. A process is said to be adiabatic, if the system does not exchange heat with the surroundings during the process
a process which takes place without any exchange of heat between a system and its surrounding
Of processes: occurring without heat transfer. Of walls: insulating. Reversible adiabatic processes are isentropic.
Without loss or gain of heat to a system. An adiabatic change is a change in volume and pressure of a parcel of gas without an exchange of heat between the parcel and its surroundings. In reference to a steam turbine, the adiabatic efficiency is the ratio of the work done per pound of steam, to the heat energy released and theoretically capable of transformation into mechanical work during the adiabatic expansion of a unit weight of steam.
adiabatic process; isentropic process. A process that neither absorbs nor releases energy into the surroundings. For example, a chemical reaction taking place in a closed thermos bottle can be considered adiabatic. Very fast processes can often be considered adiabatic with respect to heat exchange with the surroundings, because heat exchange is not instantaneous.
Referring to a process which takes place without any exchange of heat between the process system and another system or its surroundings.
Expansion or compression of a gas without loss or gain of heat content.
changes in temperature caused by the expansion (cooling) or compression (warming) of a body of air as it rises or descends in the atmosphere.
Referring to a process without the addition or removal of heat. A temperature change may come about as a result of a change in the state of a gas.
An adjective used to describe a process or transformation in which no heat is added to or allowed to escape from the system under consideration. It is used, somewhat incorrectly, to describe a mode of extrusion in which no external heat is added to the extruder although heat may be removed by cooling to keep the output temperature of the melt passing through the extruder constant. The heat input in such a process is developed by the screw as its mechanical energy is converted to thermal energy.
