Every thread turns into a discussion about the 2nd law of thermodynamics24-04-2017 18:56
spot ★★★★☆ (1323)	Notice how every thread turns into a discussion about the 2nd law of thermodynamics, I am certain that if people wished to discuss that they would be posting on a physics forum not a climate issues forum. Can we use this thread to discuss the 2nd law of thermodynamics and stop making every thread about it? IBdaMann wrote: "Air" is not a body in and of itself. Ergo it is not a blackbody. Planck's law describes the spectral density of electromagnetic radiation emitted by a black body in thermal equilibrium at a given temperature T.

What happened to your discussion about thermodynamics? You are the rocket scientist perhaps you can answer. Is a gas a blackbody? Yes and no. Gas as a whole is not a blackbody. It is a fluid and does not behave as a blackbody. Gas as molecules is a blackbody (actually greybody). These can be considered 'rigid' particles. Their emission is according to the Stefan-Boltzmann law, and Planck's law, over the domain of the emission frequencies of the molecule.

In the definition, we find it is only applicable to black bodies. So here we are wondering whether a transparent gas is a black body. Perhaps we digress. Edited on 26-04-2017 05:56

So what has the 2nd law of thermodynamics got to do with black body radiation? Spot is trying to do something weird with blackbody radiation and the Stefan-Boltzmann law or Planck's law. Yes...individual molecules are separate greybodies. Despite how ridiculous you think that is, it nevertheless works, just like individual molecules have a temperature.

Frescomexico ★★☆☆☆ (179)	The Second Law of Thermodynamics states that "in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state." With respect to the earth and its atmosphere, energy is entering the system from the sun and leaving the system towards outer space. So the 2nd law's applicability to the earth system is restricted.

Don, Could you please quit making accurate observations please ? People aren't supposed to think that the Earth can be influenced by the solar system that it is a part of. After all this also includes Conservation of Momentum as well. Linear momentum is also a conserved quantity, meaning that if a closed system is not affected by external forces, its total linear momentum cannot change. https://en.wikipedia.org/wiki/Momentum#Conservation This kind of suggests that if the Earth's orbit around the Sun were to have a minimal decrease in it's orbit then it would become warmer as a result. And our solar systems axis of rotation changes it's orientation to a different north star about every 22,000 years.

Well, specifically: "In any cyclic process the entropy will either increase or remain the same." Entropy - energy not available to do work. All this says is that in any energy exchange energy is lost. Now - where is the cyclic process?

This is a problem of contextomy. You are changing context by describing two systems and using a false equivalence between them. If you are ever in the position of 'if no energy enters or leaves the system' descriptions concerning the 2nd law, you are making this mistake. The 2nd law applies to any two or more regions of energy that are coupled together in some way. You don't discount them, and just discuss part of the system as a whole. For Earth's temperature, that is the Sun-Earth-space system. Only the space in the vicinity of Earth need be discussed for the purposes of Earth's temperature.

For Earth's temperature, that is the Sun-Earth-space system. Only the space in the vicinity of Earth need be discussed for the purposes of Earth's temperature. I stand corrected, but I'm not sure how. I am, indeed describing two systems, the earth and its atmosphere. However, I have not made them equivalent. I simply said that each had energy entering and leaving them. The definition that I cited delt with systems where no energy enters or leaves. This, obviously does not apply to either the earth or its atmosphere. Another definition is "The Second Law of Thermodynamics is about the quality of energy. It states that as energy is transferred or transformed, more and more of it is wasted. The Second Law also states that there is a natural tendency of any isolated system to degenerate into a more disordered state." The description that I cannot find is yours: "The 2nd law applies to any two or more regions of energy that are coupled together in some way". This is not to say that your description is not correct. When energy is transferred between two regions, the direction is toward greater entropy. You say "If you are ever in the position of 'if no energy enters or leaves the system' descriptions concerning the 2nd law, you are making this mistake. [the mistake of contextomy]. There is no mistake being made. In that position, the description quoted above applies: "The Second Law also states that there is a natural tendency of any isolated system to degenerate into a more disordered state."
