Adiabatische kompressibilität
In thermodynamics, an adiabatic process (Greek: adiábatos, "impassable") is a type of thermodynamic process that occurs without transferring heat or mass between the thermodynamic system and its environment. Unlike an isothermal process, an adiabatic process transfers energy to the … See more A process without transfer of heat to or from a system, so that Q = 0, is called adiabatic, and such a system is said to be adiabatically isolated. The simplifying assumption frequently made is that a process is … See more The mathematical equation for an ideal gas undergoing a reversible (i.e., no entropy generation) adiabatic process can be represented by the polytropic process equation $${\displaystyle PV^{\gamma }={\text{constant}},}$$ See more The term adiabatic (/ˌædiəˈbætɪk/) is an anglicization of the Greek term ἀδιάβατος "impassable" (used by Xenophon of rivers). It is used in the thermodynamic sense by Rankine (1866), … See more This present article is written from the viewpoint of macroscopic thermodynamics, and the word adiabatic is used in this article … See more The adiabatic compression of a gas causes a rise in temperature of the gas. Adiabatic expansion against pressure, or a spring, causes a drop in temperature. In contrast, free expansion is an isothermal process for an ideal gas. Adiabatic heating … See more An adiabat is a curve of constant entropy in a diagram. Some properties of adiabats on a P–V diagram are indicated. These properties may be … See more The adiabatic process has been important for thermodynamics since its early days. It was important in the work of Joule because it provided a way of nearly directly relating quantities of heat and work. Energy can enter or … See more WebAdiabatic compressibility measurements have been performed on a number of polymer–solvent systems and have allowed indentification of specific interactions …

WebDec 28, 2024 · Adiabatic Processes and the First Law of Thermodynamics. The first law of thermodynamics states that the change in internal energy of a system is equal to the difference of the heat added to the system and the work done by the system. In equation form, this is: \Delta E=Q-W ΔE = Q− W. Where E is the internal energy, Q is the heat … WebAdiabats are also important for the derivation of the Carnot efficiency (the maximum thermal efficiency of any thermodynamic system) which relies on two adiabatic processes. The video below (from Educational Innovations, Inc.) demonstrates an adiabatic compression: the temperature inside the chamber is increased enough to ignite the cotton.

WebAn adiabatic process is a process that changes slowly (gradually) so the system can adapt its configuration accordingly. If the system was initially in the ground state of an initial Hamiltonian H 0, it would end up in the ground state of the final Hamiltonian H 1 after the adiabatic change.
