Entropy and energy in competition,een the energy which tends to a minimum and the entropy which tends to a maximum. Those two tendencies — the energetic and the entropic one — often compete, since generally the energy favours a different distribution of matter than the entropy.NADIR 发表于 2025-3-27 04:53:21
,The zeroth law of thermodynamics — kinetic and thermodynamic temperatures,e is a tensorial relation between heat flux and entropy flux. Indeed, for a strong degree of rarefaction of the gas, the entropy flux is not related to the heat flux alone. Thermodynamics has not, however, progressed far enough to evaluate such cases.Macronutrients 发表于 2025-3-27 08:51:44
Dissipative entropy source of the earth,rologists have determined, how these fluxes are partitioned and what the temperatures of the atmospheric layers are. We use these data to determine the dissipative entropy source in the atmosphere and compare it to the dissipation of entropy by mankind. The latter is numerically negligible.落叶剂 发表于 2025-3-27 12:42:11

Origin of entropy in the work of Clausius, of its properties are very much “a physicist’s argument” starting from a loosely worded axiom. As such, the proof is looked upon with disdain by analysts. Even so, in this chapter we retrace the steps of Clausius. After all, he was first, and physicists at least find his arguments convincing; they love them!Contracture 发表于 2025-3-27 21:50:10

Statistical thermodynamics,g the thermodynamic equilibrium properties of arbitrary bodies in terms of a single function, .. Most often the partition function cannot be calculated analytically, but it may sometimes be approximated. A case where it can be determined is the case of a hydrogen atom at rest in a heat bath.Frequency 发表于 2025-3-28 03:58:44

Radiation thermodynamics,because in the stationary state the dissipative entropy source is balanced by the in- and outgoing fluxes of entropy..This chapter prepares the reader for the subsequent one in which the dissipation of the earth’s atmosphere is considered.GOAT 发表于 2025-3-28 10:40:14
Planetary atmospheres,here. This will happen earlier for a hot planet than for a cold one. Earth, which is a temperate planet in the solar system, has already lost all light gases but it holds on — for the time being — to the heavier ones like nitrogen, oxygen and argon.
