PV diagrams - part 2: Isothermal, isometric, adiabatic processes

Adiabatic compressions actually occur in the cylinders of a car, where the compressions of the gas-air mixture take place so quickly that there is no time for the mixture to exchange heat with its environment. Nevertheless, because work is done on the mixture during the compression, its temperature does rise significantly. In fact, the temperature increases can be so large that the mixture can explode without the addition of a spark. Another interesting adiabatic process is the free expansion of a gas. When the membrane is punctured, gas rushes into the empty side of the container, thereby expanding freely. If the gas is ideal, the internal energy depends only on the temperature. Therefore, when an ideal gas expands freely, its temperature does not change; this is also called a Joule expansion.

In thermodynamics , an adiabatic process is a type of thermodynamic process which occurs without transferring heat or mass between the system and its surroundings. Unlike an isothermal process , an adiabatic process transfers energy to the surroundings only as work. Some chemical and physical processes occur too rapidly for energy to enter or leave the system as heat, allowing a convenient "adiabatic approximation". In meteorology and oceanography , adiabatic cooling produces condensation of moisture or salinity, oversaturating the parcel. Therefore, the excess must be removed. There, the process becomes a pseudo-adiabatic process whereby the liquid water or salt that condenses is assumed to be removed upon formation by idealized instantaneous precipitation.

In fact, isothermal means the temperature remains constant, and adiabatic means that there are no heat transfer processes. All four processes can be presented on a p-V graph the blue lines are isotherms — lines showing the points at the same temperature :. From the first law of thermodynamics :. Substitute in the definitions of heat capacity and work:. These equations are used a lot in Carnot cycles and Otto cycles.


Isothermal process is a process that happens under constant temperature, but other parameters regarding the system can be changed.

Isothermal process is a process that happens under constant temperature, but other parameters regarding the system can be changed accordingly. Adiabatic process describes a process where no heat transfer occurs between a system and its surrounding. Here, the temperature of the system should be changed in order to avoid any heat transfer. This indicates that the main difference between isothermal and adiabatic process is that isothermal process occurs under constant temperature whereas adiabatic process occurs under varying temperature.

This typically occurs when a system is in contact with an outside thermal reservoir , and the change in the system will occur slowly enough to allow the system to continue to adjust to the temperature of the reservoir through heat exchange see quasi-equilibrium. Simply, we can say that in isothermal process. Isothermal processes can occur in any kind of system that has some means of regulating the temperature, including highly structured machines , and even living cells. Some parts of the cycles of some heat engines are carried out isothermally for example, in the Carnot cycle.

Мощенный брусчаткой тротуар под ногами постепенно сливался в одну темную гладкую полосу. Быстро опускалась ночь. Капля Росы. Что-то в этом абсурдном имени тревожно сверлило его мозг. Капля Росы. Он слышал приятный голос сеньора Ролдана из агентства сопровождения Белена.

Стоящая перед ним задача была крайне деликатна и требовала массу времени - вписать скрытый черный ход в сложный алгоритм и добавить невидимый ключ в Интернете. Тайна имела первостепенное значение. Любое подозрение об изменении Цифровой крепости могло разрушить весь замысел коммандера. Только сейчас она поняла, почему он настаивал на том, чтобы ТРАНСТЕКСТ продолжал работать. Если Цифровой крепости суждено стать любимой игрушкой АНБ, Стратмор хотел убедиться, что взломать ее невозможно. - Ты по-прежнему хочешь уйти.

Да, он сумел прочитать эти слова, и их смысл был предельно ясен. Прочитав их, Беккер прокрутил в памяти все события последних двенадцати часов.

    Because heat engines may go through a complex sequence of steps, a simplified model is often used to illustrate the principles of thermodynamics.
