(Biyokimya) Adyabatik, Termodinamikte çalışma akışkanında işi ve kütle kaybının veya kazancının olmadığı haldeki süreçtir. Adyabatik bir ortam oluşturabilmek için sınırlanmış alanın işi ve kütle geçişine karşı tamamı ile yalıtılmış edilmiş olması gereklidir.Adyabatik bir süreçte işi ve kütle değişimi olmadığı için toplam iç enerji değişimi sıfırdır. Başka bir deyişle tam bir yalıtım vardır. Örneğin; bir pistonun bir gazı sıkıştırması esnasında, silindirin duvarlarının tamamen yalıtılmış olması durumunda sıkıştırma işleminin adyabatik olduğu söylenebilir. Ama gerçekte tamamen adyabatik bir sistem oluşturmak mümkün değildir. Termodinamikte teorik olarak bu yönde kabuller yapılarak çalışılır. Atmosferde düşey adyabat ve yatay adyabat vardır
Dışarıyla işi alış verisi olmaksızın suyu hava içerisine buharlaştırma. Hava ve suyun duyulur ısısı, havaya karışan buharın gizli ısısı haline gelir ve sıcaklıklar düşerek eşitlenir
(Askeri) ADYABATİK GRAFİK: Meteoroloji istasyonları tarafından kullanılan bir grafik. Bu grafiğin üzerindeki yukarı değer hatları basıncın 0.288'nci kuvvete ref'ine eşittir ve aşağıdan yukarı çıkıldıkça küçülür. Sağ değerler ise, sıcaklığı gösteren ve başlangıç noktasından itibaren sağa doğru büyüyen sayısal kıymetlerdir. Adyabatik grafiğin üzerinde, sabit potansiyel sıcaklık gösteren kuru adyabatlar (dry adiabats), doygun adyabatlar (saturated adiabats) ve meyilli hatlar da mevcuttur
(Askeri) ADYABATİK SICAKLIK DÜŞÜŞ ORANI: Bir standart atmosferdeki sıcaklığın yüksekliğine göre değişme oranı olup, nispi rutubeti %100 den az olan hava şartlarına uygulanır. Bu oran 100 metrede 1 derecedir
Talk of dynamic compression and adiabatic gradients didn't carry as much weight as the certainty of its conscious intent.
Descriptive of a system or process in which no gain or loss of heat occurs That is, at constant entropy
Applies to a thermodynamic process during which no heat is added to or withdrawn from the body or system concerned In the atmosphere, adiabatic changes of temperature occur only in consequence of compression or expansion accompanying an increase or decrease of atmospheric pressure Thus, a descending body of air undergoes compression and adiabatic cooling
a process which takes place without any exchange of heat between a system and its surrounding
Refers to a process that occurs without the addition or removal of heat This is considered an ideal or theoretical process in which there is absolutely no heat exchange between a gas and its environment However, temperature changes may occur as a result of a change of state of a gas
Term applied to expansion or compression of a gas occurring without gain or loss of heat
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
Of or denoting change in volume or pressure, with no heat gain or loss with the surrounding air
The frequency for a transition where both upper and lower states have no vibrational quanta (i e , a transition between zero-point levels)
An adiabatic process is one in which there is no exchange of heat with the surroundings The relationship of pressure and volume when a gas or other fluid is compressed or expanded with no loss or gain of heat In an adiabatic process, compression causes an increase in temperature and expansion a decrease in temperature
Term applied to expansion or compression of a gas occurring without gain or loss of heat
in thermal isolation A thermal process is said to be adiabatic if no heat enters or leaves the system in which it is occurring
A term indicating that no heat is lost or gained by a material being subjected to a thermodynamic process
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
invariants are quantities associated with approximately periodic motions which almost do not change, and are similarly useful They are important in calculating the way ions and electrons move in a magnetic field
In thermodynamics, an adiabatic process or an isocaloric process is a thermodynamic process in which no heat is transferred to or from the working fluid. The term "adiabatic" literally means impassable, coming from the Greek roots ἀ- ("not"), διὰ- ("through"), and βαῖνειν ("to pass"); this etymology corresponds here to an absence of heat transfer. Conversely, a process that involves heat transfer (addition or loss of heat to the surroundings) is generally called diabatic. Although the terms adiabatic and isocaloric can often be interchanged, adiabatic processes may be considered a subset of isocaloric processes; the remaining complement subset of isocaloric processes being processes where net heat transfer does not diverge regionally such as in an idealized case with mediums of infinite thermal conductivity or non-existent thermal capacity
A thermodynamic change of state of a system such that no heat or mass is transferred across the boundaries of the system In an adiabatic process, expansion always results in cooling, and compression in warming
A thermodynamic change of state in a system in which there is no transfer of heat or mass across the boundaries of the system In an adiabatic process, compression always results in warming, expansion in cooling Compare to diabatic process
A thermodynamic change of state of a system in which there is no transfer of heat or mass across the boundaries of the system In an adiabatic process, compression always results in warming, expansion in cooling In meteorology the adiabatic process often is also taken to be a reversible process For many purposes, changes of state in the free atmosphere over periods of two days or less are assumed to be adiabatic
A process that occurs without a given system (such as a parcel of air) exchanging energy with its surroundings In such a process, expansion always results in cooling and compression always results in warming
is a process during which there is no heat transfer The word adiabatic comes from the Greek word adiabatos, which means not to be passed is a process during which there is no heat transfer The word adiabatic comes from the Greek word adiabatos, which means not to be passed
A thermodynamic change of state in a system in which there is no transfer of heat or mass across the boundaries of the system In this process, compression will result in warming and expansion will result in cooling
