Short videos covering the full range of topics in an undergraduate physical chemistry course, in a "Boltzmann-first" order.
Start here: youtube.com/watch?v=OVVcePiou2I, then follow the link at the end of each video to work through the whole course. There are also playlists for each section of the course:
Introduction
Probability
Entropy
Optimization
Boltzmann
Quantum Mechanics
One-Dimensional Particle in a Box
Postulates of Quantum Mechanics
Partition Function
3D Particle in a Box
Ideal Gas
Kinetic Thy of Gases
Gases
Thermodynamic State
Rigid Rotor
Harmonic Oscillator
Diatomic Molecules
Spectroscopy
Solids
Symmetry
Spontaneity
Free Energy
Thermo. Relationships
Phase Equilibria
Solutions
Electrolytic Solutions
Hydrogen Atom
Many-Electron Atoms
Nuclei
Chemical Equilibrium
Surfaces
Lasers
Most can stand on their own, and have links back to earlier material if you need a refresher, so feel free to jump in where you like.
Happy PChem-ing!
