The entropy of systems

Tom,

Where ever I say: change in velocity, replace by: time rate of change of velocity.

Now would you please answer my question?
<b>HOW</b> and <b>WHY</b> does energy vary in a system?

Here is my answer:

HOW: because the atom continually releases energy (more than it absorbs) See entropy increasing phenomena in the links I have been posting-

WHY: Because a system is NOT in equilibrium (It accelerates)

Your answer please:...

LB and I have only commented on the most glaring. Beyond that, you have confused "energy" and "entropy", which are quite different concepts. So I don't even understand your question. Do you want to know the origin of energy or entropy? Both matters are addressed in the 20-author 2002 book "Pushing Gravity". The former arises from elysium, the latter is an attribute of different types of mediums. -|Tom|-

If entropy increases with time, then potential energy has to become less.
1) Do you agree with this ?
This concept is what I am trying to show in these energy equations.

2) Are you saying that entropy has nothing to do with the energy level of the atom?

3) According to you, does entropy increase also mean temperature increase?

4) If a natural system accelerates, is it caused by an imbalance in energy or entropy?

5) should I stop hassling you guys?

Here are my answers (If you don't mind, I would like to compare with your's or Larry's):
1) yes
2) yes, the atom is affected by entropy.
3) yes
4) both, one affects the other.
5) maybe this is entertainment for some.[8D]

It has nothing to do with the energy levels of atoms.

If air is trapped in half of a chamber, and an internal window is opened so that air expands to fill both halves of the chamber, the entropy has increased while the temperature would remain the same or decrease.

[GD] " ... does entropy increase also mean temperature increase?"

[tvf] " No. It has nothing to do with temperature. If air is trapped in half of a chamber, and an internal window is opened so that air expands to fill both halves of the chamber, the entropy has increased while the temperature would remain the same or decrease."

Here is a slightly modified version of tvf's divided chamber demonstration system. Before opening the internal door one side of the chamber contains pure helium, the other side pure neon. The temperature and pressure are the same on both sides. After opening the door the atoms of helium and neon begin to mix, and entropy begins to increase. As time passes the atoms continue to mix and entropy increases more. At some point the concentration of the two gasses is the same everywhere in the chamber and entropy stops increasing. The temperature and pressure in both sides of the chamber have remained constant all the while. Before, during, and after the change in entropy.

Velocity and acceleration of the system have also not changed. Ditto for voltage, gravitational potential energy, chemical potential energy, charge, mass, volume, etc. In fact, just about the the only thing that did change was the system's entropy.

Does this help?

Chr..., I never thought we were so far apart in this thinking process.

Therefore I wasn't able to communicate properly my views on this subject.

I still don't think today's definitions in physics properly describe our universe? (... physical anomalies, dark energy, dark matter, eleven dimension universe, etc...)

I'm going to need more time...
