If a bar of metal's atoms are heated at one end then if the heat is

even in a solid are rotating and some form of torque interaction is
carrying through the metal thus allowing such a slow conduction rate
as is observed far below the speed of sound.

Interesting, you appear to have learned nothing in the last few days.

Same idiocies as before - copies and pasted with no allowance for
learning.


It seems that the most advanced form of thermal analysis is in the
phonon realm.
However, they ignore the issue as stated above.

That's because the issue does not exist.

Phonons are lattice vibrations and as such propagate at a well
established velocity.

The phrase "dispersion relation" would be useful right about now, but
that is only for people who know what the phrase means.

At least this is my current interpretation and so far noone has
corrected me.

Would anything change if I did? You are still repeating the same
idiocy as on the 21st.

In the application to thermodynamics an interesting phenomeon that can
be taken as support of my own theory is stated in C. Kittel's
Introduction To Solid State Physics:

Oh this will be fun - I own this book and have studied a significant
portion of it. At least you made the effort to open the book...

"In magnetic solids there is a large contribution to the heat
capacity over the temperature range in which the magnetic moments
bevome ordered. A change in the degree of order means a change in the
entropy and thus a contributioni to the heat capacity. Below 0.1K the
ordering of nuclear moments may give very large heat capacities."
( From Chapter 5. PHONONS II. THERMAL PROPERTIES, LATTICE HEAT
CAPACITY, third experimental fact. )

*scratches head*

Why is the heat capacity of a quantum solid anywhere near relevant?
Why are you even reading Chapter 5 when there were 4 other chapters -
all of which are more relevant?

Do you understand the material of chapter 1? If I ask you to tell me
the difference between a face centered cubic lattice and a body
centered cubic lattice, could you?

Chapter 2? Could you tell me how big their respective primitive cells
are?

Chapter 3? Can you do *any* of the problems at the end of the chapter?

Chapter 4? Why did you skip over the chapter that explicitly talks
about the propagation of plane waves in the solid, as well as their
velocities and relevant dispersion relations in the high and low
frequency limits?


Still as I plunder the text for a treatment of heat propagation rate I
see no address of my concern of the speed of a lattice vibration
versus the speed of propagation of heat. This is a bad conflict and
how it can go unspoken troubles me. Can anyone help me here? It would
seem that the curve-fitters have been hard at work in this area.

Your stupidity is breathtaking. You skipped right over chapter 4 which
talks ALL ABOUT how fast the plane waves travel.

The least you can do when quoting a textbook is read the fucking table
of contents.

If you want to know how heat propagates, take the theory developed in
any course which develops the heat equation from first principles then
apply them to equations (1) - (3) in Chapter 4 plus whatever else is
required.

Do you even know how equation (4) is obtained from the previous
equations? Did you even look at that section of the book, or did you
skip straight to Chapter 5 to rage against physics?
