We answered that 11 pages ago/Quote from: Bored chemist on 19/03/2022 11:45:18Quote from: hamdani yusuf on 19/03/2022 03:56:58The question is, what distinguishes thermal energy from kinetic energy?The motion having some sort of structure, rather than being random. Essentially, it's an effect of entropy.
Quote from: hamdani yusuf on 26/07/2022 14:32:17Is there a magnitude of negative temperature? Can an object have more negative temperature than another object? What would happen if they interact?

QuoteHow is the temperature measured before reaching equilibrium?Sometimes you can do this spectroscopically.Sometimes it's impossible.

If you haven't got it sorted out after 12 pages of coaching, you probably never will.
Afaik, thermal energy has highest entropy among other kinds of energy, which makes it the most random form.Black body radiation is the simplest spectral distribution of thermal electromagnetic radiation. The object's temperature can be calculated from the peak frequency. But most objects are not black body. Spectrum of low pressure gas has much different shape than black body radiation.
How can we get negative temperature?

I answered this earlier.

Quote from: Bored chemist on 31/07/2022 10:42:48I answered this earlier.If you think that you already understand something by simply pointing to an online article, which mentions it, you are likely being delusional. If you really understand it, you should be able to answer these questions easily.

You have repeatedly demonstrated that you don't even understand the easy stuff.Why waste everyone's time with the more sophisticated bits?

Pretending to know something that you don't know is not a scientific attitude.
What you said is true.However, it's unconnected to what you quoted me as saying.Why did you quote me?

But so far, you failed to answer some simple questions, like these.
How do we know the temperature of the cube?
you don't understand the simple stuff
Talking about heat shield, you might find this video quite informative.

Could you at least try to think about your questions a bit before you ask them?
