Heat is vibration of molecules. It's quantum stuff. All air molecules vibrate. Whether it's O2 or N2 or CH4 or CO2. You name it. All air molecules have heat and conduct heat. There's nothing special about certain gasses and not others.

Yes... Everything has thermal energy, barring photons and subatomic particles.

But different substances act differently. Some substances have higher specific heats. Some substances conduct heat better. And some substances, in their gaseous form, have different absorption and emission spectra.

Don't take this as a criticism. I am not saying that the above says absolutely nothing. I am not saying that. Do you really mean to say that different substances have different properties?

Anyway, all matter has thermal energy. All matter radiates per its temperature which is determined by its thermal energy. This may or may not be God's will, I'm not sure.

Haven't you ever heard of a 'hot idea', a 'hot babe', or a 'hot time'?

I don't consider a 'cold bitch' to be about love.
I don't consider an 'idea placed on ice' to be a great idea.
I don't consider a clock stopped cold to be about time, but taking time for a 'cold one' certainly would be.

Gases do not radiate as per Planck's Law. The radiation from a gas is dependent on both temperature and identity.

Would you take it personally if I were to say that is one of the stupidest things I have ever read? I'm at a loss at the moment for an appropriate sugar-coating.

The radiation of any gas is per it's temperature and domain of wavelengths, exactly per Planck's law.

Identity? Really? Who are you letting do your thinking for you? If you're going to do that you should at least let a SMART person do your thinking for you, not a clueless moron.

Identity, as in chemical identity, thank you very much. An accepted word.

Planck's Law describes a distribution, which the emission spectra of gases do not demonstrate. It thus does not apply to them. Planck's Law does not work when dealing with gases, just like how the IGL works okay for some things, but not necessarily for all.



There. An example of a gas (mercury and halides, gaseous) that does not demonstrate Planck's Law. If that example doesn't work, I'll find another and another and another. Planck's Law is more like the IGL than the Laws of Thermodynamics.

False.

Planck's is expressed in math. All the rules of math still apply.

Go back through your notes and look up the terms "domain" and "range."

We are otherwise done on this topic. You are arguing that you somehow get to make up your own rules.

According to my sources; https://en.wikipedia.org/wiki/Planck%27s_law
Planck's law describes the spectral density of electromagnetic radiation emitted by a black body in thermal equilibrium at a given temperature T.


According toIBdaMann ;
"Air" is not a body in and of itself. Ergo it is not a blackbody.

There is no temperature for which Planck's law gives a graph of radiance against wavelength with more than one peak. Therefore any emission spectrum with more than a single peak does not follow Planck's law.

They're at the same temperature, so that can't be it. GASP! Could it be that different substances radiate differently, past, even, their emissivity? Could it be that substances have EMISSION SPECTRA that CANNOT be predicted by Planck's Law?

Nah, it couldn't. I eagerly await IB or Into's response. Maybe it won't include an "argument from insult"!

Did you look up the term "domain" ? Do you believe you can apply the concept of "the domain of radiating wavelengths" for any given substance since gases clearly have differing radiating domains?

Find a gas whose energy radiation at a given temperature and wavelength which is in its domain is measured to be something other than what Planck's specifies and you will have a gas that does not radiate per Planck's.

We have a graph of a mixture of gaseous metals. If that is not good enough, we can find another - but according to you, the identity of a radiating substance only matters to the point of changing emissivity, and that only scales the energy of the radiation; it does not move the peak. Thus, if I can demonstrate that Planck's Law predicts that all bodies of even temperature will have an emission spectrum only one local maximum (or peak, for those who haven't done Calc), and that a body of even temperature demonstrates an emission spectrum with multiple local maxima, then I have proved you wrong. That is, I will show that Planck's Law predicts that there is only one local maximum, making it the global maximum. This can be reworded to say that "any local maximum in a Planckian emission spectrum will be the global maximum." If I can demonstrate that there exist multiple local maxima in an emission spectrum, or that there exist points with y-value greater than or equal to a local maximum, then in combination with the proof of my statement about Planck's Law, I will have proven you wrong.

Do you agree with this?

Okay, that equation is very hard to find the derivative of. I mean REALLY hard. I got something out of it, but it was convoluted and I couldn't figure out when it became 0.

So can we just agree that Planckian distributions never have more than one local maxima?

"Air" is not a body in and of itself. Ergo it is not a blackbody.


Go study this law from someplace besides the wasteland that is Wikipedia.


I thought you hate logical fallacy, saying something is wrong because its from Wikipedia and only because its from Wikipedia is a logical fallacy, I'm not claiming its infallible just in this case it's correct. Can you offer a source that contradicts it?

Thought not.

No, it's not a logical fallacy to request a more trustworthy source.

Planck's Law will never predict multiple local maxima. Correct?

Let us look at the following graph:



Let's assume that this graph follows Planck's Law. There is a local maximum at ~600 nm, with a value of 80 (somethings). Planck's Law will never predict a value of 80 or above for any other wavelength. This includes 550 nm. I don't need to calculate it - because there exists a local maximum somewhere else, Planck's Law will preserve that as the global maximum. So surely 550 nm has a power of <80, right?

No. It has a power of 100.

Take that. You called me logically and scientifically illiterate - and yet you couldn't even notice the difference between two graphs. Hm. Maybe you are at the left side of the D-K graph.

Is there a source that will tell you different?

I thought you were on my side anyway.
