Entropy increase seems inevitable in the macro-mechanical universe
simply because of the Law of Large Numbers. It's a probability thing,
and a consequence of quantum states in e-n electrons.
The role of relativity in this, as in the mass-energy equivalence, I
don't have the knowledge to comment upon it.
Simply, whether radiated heat from our body will change entrapy of
universe minutely or not?
That seems to be the general consensus, but cosmologists can't even
define comprehensible limits to the universe yet

Can you tell me the fate of emmited/reflected light from an object?
Emission of e-m radiation is normally due to energy level shifts in e-
n electrons. I would guess that the resulting redistribution of
internal energy within the emitter would signal an entropy increase.
But I'm only guessing. The amswer belongs to quantum mechanics, of
which I know very little..

In view of thermodynamic equilibrium, it looks quite logical. This may
suggest any of out activity can radiate or absorb heat so may effect
entropy of universe. As such whole universe may be inter-linked by it.

Entropy is a property that is statistically based. It can be defined in
thermodynams or in statistical mechanics. In stat mech it is defined by
the equation S = -kln(omega) where omega is a count of the number of

I think you mean S = + k ln(omega). Since omega is great than one, its
natural log is positive, as is the Boltzmann constant k. The entropy
can NEVER be negative; in fact, it can't even be zero, except at
absolute zero for a perfect crystalline material (3rd Law), and, of
course, absolute zero is unreachable.

Note that this definition of entropy is only true for the
microcanonical ensemble.

Yes entropy can not be negative. But I think some activities in atoms/
molecules still continue even at absolute zero. I can't say that
contribute to temp. and entropy or not.

Molecular vibrations continue at absolute zero, but they are non-
entropic.



Still, entropy can't be negative but it can be decreased or increased
depending on temperature.

Are our all activities and all things and beings connected to this
free energy, entropy, heat, temp.and motions by their specific
activities and makeups to overall free energy and entropy...alike
local effects related to systemic effect in our body?

Yes.
Thanks.
Whether free energy is heat or kinetic energy or useful energy AND
Stored/Useless energy is Potential Energy stored in various matters/
substances?

Whether entropy and free energy is inversely related to potential
energy and directly to kinetic energy?


Btw, whether free energy, entropy and theromodynamics are dependant
on proportions of disorganized and organized (stored) energy ?

Thinking in terms of "organized" or "disorganized" is not very
helpful. Better to think of entropy as q/T, where q is the heat
transfered, and T is the temperature at which it is transfered. If no
heat is transfered (q=0), the process is adiabatic, and the entropy
doesn't change.
Whether magnetism and light do not effect entropy?




states permitted for the system. So if the number of states permitted
increases in a change then the entropy must also increase.
