Maybe we should define what heat is:

Heat results from the atom undergoing a potential change. It is the atom releasing some or all of its energy.

Since heat is relative to what is cold, and the coldest is zero kelvin, then an atom whose potential or activity produces 1 kelvin and above may be considered as heat.

We have already defined a change of potential of the atom as a change of its entropy. Then the measure of heat released by the atom is also a measure of its entropy.

It seems to me an atom can have the same entrophy at any temperature and that is why I wonder what you think about how entrophy changes in the atom when temperature rises or falls. So, you say the entrophy of an atom rises as the temperature rises? That seems to mean a hot atom has more entrophy than a cold atom. Is that how you see this? Why is it so hard to get this simple agreement?

Jim,

I agree with you that entropy change is the same as saying temperature change.
After all, the heat we record on our instruments comes from the atom.

A low entropy atom releases less energy or is less active than a high entropy atom.

What we cannot say though, is that entropy remains the same.
Saying that entropy remains the same would mean that momentum is conserved, that time is at a standstill, that things would never age.

Matter accelerates, therefore it is not in equilibrium !

It seems the universe we observe today is "ordered" in a such a way that I would call a "controlled disorder".

I am clearly not saying temperature change means entrophy change-you are saying that. I'm trying to agree that is what you are saying. What I am saying is entrophy does not exist in an atom at all. The atom can be located anywhere on an entrophy diagram reguardless of what the temperature is. If you think temperature and entrophy are somehow more or less equal then we differ on that too.

Jim,

I agree that we disagree.

Lets take the sun for example. Is this not the best example of entropy ?
It has a definite number of atoms and it will take a definite amount of time to convert these atoms into energy. This process is in one direction only.

The sun is now converting millions of tons of matter into energy every second.
The atom is transformed irreversibly and this energy will never be used again.

Please tell me how the atom remains stable at 1 million kelvin for example?

How do you get to E=mc^2 from entrophy? You made a transfer from one train to another and I only want to chat about entrophy here. As a matter of fact I asked you to move this detail to a new thread early on and leave this thread for the detail that now is lost. I made a mistake so now this thread is about entrophy thanks to you. If you want to start another topic don't do it on this thread.
