NettetJoule–Thomson-effekt er temperaturforandring i en gass som følge av at den langsomt strømmer gjennom en form for åpning til et sted med lavere trykk. Åpningen kan være … NettetThe Joule expansion(also called free expansion) is an irreversible processin thermodynamicsin which a volume of gas is kept in one side of a thermally isolated container (via a small partition), with the other side of the container being evacuated.

It can be described as follows: μ μ J T = ∂ T …
NettetThe internal energy of an ideal gas is independent of its volume and pressure and only depends on its temperature, according to Joule's second law. αT = 1 for an ideal gas characterized by proper microscopic postulates, implying that the temperature change of such an ideal gas during a Joule–Thomson expansion is zero.
Nettet19. jul. 2024 · The Joule-Thomson effect describes the decrease in temperature of real gases when they expand against a lower pressure! In the article Free expansion of an ideal gas in a vacuum it was explained that the free expansion of a gas against a vacuum taking place in an (ideal) adiabatic system is an isothermal process. For this purpose, a gas … NettetWe characterise the critical point for condensation and observe saturation of the thermal component in a partially condensed cloud, in agreement with Einstein’s textbook picture of a purely statistical phase transition. Finally, we observe the quantum Joule-Thomson effect, namely isoenthalpic cooling of an (essentially) ideal gas.
NettetAt Thomson’s recommendation, in February 1867 Tait sent Helmholtz the first two draft chapters of his ‘little work’ on the history of thermodynamics. He said his purpose was to give Joule and Thomson greater credit than they …
