Is number of states correlated with entropy?
@pazzy768
@pazzy768 4 ай бұрын
So the entropy, S, is given by S = k_B * ln(w) Where w is known as the macrostate multiplicity (ie the number of microstates for given marcostate). So a given system in thermodynamic equilibrium will want to maximise this quantity - and so will occupy the state which has the greatest number of choices!

I'm confused about how you're defining degrees of freedom. For an ideal gas, we had 3 degrees of freedom, but in the metal lattice you show in the derivation of the Dulong-Petit Law, you say there are 6 degrees of freedom? Why the difference? Furthermore, you mention at the end that in future videos there will be elements of QM. You mention that we will now assume particles are indistinguishable, but I thought we were assuming that for a while now? Isn't that what the point of the Gibbs factor (1/N!) is? These videos have been excellent in all other aspects and have hugely helped me navigate this difficult subject.
@pazzy768
@pazzy768 4 ай бұрын
For the ideal gas, there are indeed 3 DOF. These include: motion in the x direction, motion in the y direction and motion in the z direction. Mathematically, this can be written as a Hamiltonian which has three momentum terms: p_x^2, p_y^2, p_z^2, one for each cartesian coordinate. In the case of an atom in a metal lattice, we model the atom as a harmonic oscillator. This means that in addition to the three momentum motion terms in the Hamiltonian, there are three additional terms which correspond to the elastic potential energy stored when an atom deviates from its equilibrium position in the lattice. Think the formula for the potential energy stored in a spring ½*k*x^2. But because we're in three dimensions, it would be ½*k*(x^2+y^2+z^2). These 3 terms, alongside the 3 momentum terms give rise to 6 degrees of freedom in total in the metal lattice. The key difference is, in an ideal gas there is no potential experienced by the particles, whereas in a lattice the atoms are bound by potentials caused by other atoms. I'll get back to the second part of your question when I rewatch my video!

7:05 Wrong. The issue is that the further you go up in frequency, the more energy would be expected to radiated out from the black body. The limit would be infinite energy emitted by the black body, and THAT is the "carastrophe." Also, the word "ultraviolet" was their time's way of describing photons beyond visible light. You're welcome.

Hey, nice video but Gibbs entropy formula does NOT have a capital N term. You missed saying that entropy is linear, and that you are takin N elements/systems, hence the entropy of ONE element / system is the actual formula of Gibbs, which does not have N, because you have to divide by N.

Boltzmann Distribution Hey Pazzy, does this model look like it might describe the math in your lecture? Thanks for your well produced video. Your viewers might enjoy seeing my personal amateur science project. Sorry if it’s not a well produced video I need to do better. It might be a good visual aid that the math describes. See linked below. It uses a sheet of spring-like material buckled from the ends to form a Gaussian curve. The area under the curve represents the energy in the system. The sheet of material represents a field with the ends bounded. Seeing the mechanical effect may takes some of the mystery of what the math for your students. See the load verse deflection graph in the white paper found elsewhere on my KZbin channel. kzbin.info/www/bejne/raOlpKSfepWpfZYsi=waT8lY2iX-wJdjO3

Hi, great video! I had a question though - when you use "quasistatic" in this video, is this the same as being reversible? I would think that a process that happens very slowly such that the system is in equilbrium at all times would be reversible?
@pazzy768
@pazzy768 7 ай бұрын
Hi, thanks! I don’t think they’re quite the same thing. Quasistatic refers to the system being in constant equilibrium with its environment, and that you’re changing a parameter slowly enough so that the system and environment are never unbalanced. However once you’re getting into reversibility then the second law of thermodynamics would start to kick in, which is non time symmetric. Technically you can go back and forth along the same part of (eg.) a Carnot cycle but in reality the efficiency of that process will never be more than the ideal efficiency, which is already less than 1.
