Still tilting at that windmill?
"A) From thermodynamic tables, the mole entropy of silver at standard
conditions S(Ag, cr) = 42.55 J K-1 mol-1 is bigger than that of
aluminum S(Al, cr) = 28.30 J K-1 mol-1. Does it mean that there is
more disorder in silver as in aluminium?"
Yes, there is more disorder in the sense that raising the temperature
of a mole of Ag 1deg increases the number of accessible conduction
electron states available more than does raising the temperature of a
mole of Al does.
I agree that disorder is not necessarily a good metaphor for entropy.
But dispersal of energy isn't always intuitively equal to entropy
either. Consider dissolving ammonium nitrate in water. The process is
endothermic, so the temperature drops and energy is absorbed, but
the process goes spontaneously because the entropy increases; the are
a lot more microstates accessible in the solution even at the lower
temperature.
You'd better look at what biologist say. For example:
http://www.icr.org/article/270/
“and that the idea of their improving rather than harming organisms is
contrary to the Second Law of Thermodynamics, which tells us that matter
and energy naturally tend toward greater randomness rather than greater
order and complexity.”
Do you like it?
