Why are you conflating the movement of energy with the ordering of matter?

For the same reason entropy conflate's the movement of energy with the
"disorder" of matter.

Take your most basic system of entropy.

2 atoms. (a & b)

Atom (a) is in energy level 1, and Atom (b) is in energy level 2.

Atom (a) in more highly ordered. (smaller volume)

Atom (b) now transferres a photon to Atom (a).

According to thermodynamics, because of the transfer of thermal
energy, the entropy of this system *MUST* increase. But it CANT!

Atom (a) receives the photon from (b). (Transfer of thermal energy
therefore increased entropy), but at the COST of rearranged
organisation between the two atoms.

Atom (a) is now in energy level 2, and is thus more *DISORGANISED* as
you would expect!

HOWEVER & MORE IMPORTANTLY!!!!!

Atom (b) is now in energy level 1, and has become more organised. Due
to its (NOW) smaller volume.




I don't know much about thermodynamics, but it seems to me that atom
(b), if it has an electron at a higher energy level, would be in a
more ordered state than atom (a).

Your right, my bad.

Because the electron in (b) has a larger orbital radius, it takes up a
greater volume than Atom (a).

Because it has a larger volume, it has fewer degrees of freedom in any
confined space, than Atom (a) would. It is thus more organised.

But the conservation of entropy is still applied, between the two
atoms.
