A process in which heat does not enter or leave a system. In the atmospheric sciences, adiabatic processes are often used to model internal energy changes in rising and descending parcels of air in th [..]

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 [..]

Changes in temperature caused by the expansion (cooling) or compression (warming) of a body of air as it rises or descends in the atmosphere, with no exchange of heat with the surrounding air.

1838, from Greek adiabatos "not to be passed through," from a- "not" + dia "through" (see dia-) + batos "passable," from bainein "to go" (see come).

having to do with a process or chemical reaction that occurs without the gain or loss of heat.

change in temperature due to expansion or contraction of a parcel of air which thus change the pressure and therefore the temperature. No heat transfer between the air parcel and the surrounding air.

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.

A condiiton in which no heat transfer occurs to or from the environment surrounding the sample, including the sample container. (HSE 2000)

Any change in which there is no gain or loss of heat.

Not involving an exchange of heat between the system said to be adiabatic and the rest of the universe.

(adj) occurring without loss or gain of heat

An absence of heat transfer. In thermodynamics, adiabatic heating and cooling are processes that commonly occur due to changes in hydrostatic pressure. When a substance undergoes a pressure change, compression or expansion takes place, resulting in a temperature change. In an adiabatic system, the temperature change occurs without the addition or l [..]

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 th [..]

Changes in temperature

<radiobiology> Not involving an exchange of heat between the system said to be adiabatic and the rest of the universe. (09 Oct 1997)

Changes in temperature caused by the expansion (cooling) or compression (warming) of a body of air as it rises or descends in the atmosphere, with no exchange of heat with the surrounding air.

A process in which no heat is gained or lost

A thermodynamic process in which no heat is transferred to the surrounding air. In an adiabatic process, compression of an air parcel results in an increase in temperature, while expansion results in a decrease in temperature.

A process where temperature changes occur in a 'system', without heat being supplied to, or lost from that system. In meteorology, used in connection with changes involving air parcels movin [..]

changes in temperature

A thermal process occuring without any exchange of heat.

Changes in temperature caused by the expansion (cooling) or compression (warming) of a body of air as it rises or descends in the atmosphere, with no exchange of heat with the surrounding air.

Occurring with no addition or loss of heat from the system under consideration.

process taking place without heat entering or leaving the system.

A change in temperature due to expansion or contraction of a parcel of air.

change of volume and pressure of a gas in which there is no heat gained or lost by the gas

A fancy term to describe changes in the temperature of air due to expansion or compression. Air sinks, it is compressed and warmed adiabatically, without any exchange of heat with the outside environment (although there's always some mixing around the edges). Air rises, it expands and cools.
