Lecture 8 Notes: Collision Theory
Collision Theory was invented by Maxwell (1831 - 1879) and Boltzmann (1844
- 1906) in the mid to late 19th century. Viciously attacked until ~1900-1910, when

Lecture 9 Notes: Dilute Hard Gases
The mean free path. The mean free path is the average distance a particle traverses
before it experiences a collision. In Lecture #31 we determined the average colli
Lecture 6 Notes: Large Density Points
We know how to think about the electronic structure of a molecule we know the
orbitals, their energies, their occupancies but with a metal, which we treat as one
Lecture 7 Notes: Electron Theory
In the free electron theory we ignored all effects of the nuclei in the
lattice, utilizing a particle-in-the-box approach sans a potential. In the band theory
of solid
Lecture 10 Notes: Net Mass Flux
We begin by considering the important case of diffusion. Diffusion is a very
important transport property for chemists because it describes the mass transport
necessary

An atomic description of the vibrations of a solid. This will be a more
realisticdescription than Einsteins or Debyes, which are continuum models. Debyes

Intermolecular potentials are interactions between molecules up to this point, particles
are treated as independent, ideal particles that do not interact.
