The site is a free e-book/self-paced open online course (SPOOC) on chemical thermodynamics/statistical mechanics consisting of video-lectures and associated Powerpoint slides as well as problem sets.
The material is the thermodynamics part of the physical chemistry course for nano-science students, which I co-teach at the University of Copenhagen.
This is a work in progress!
Currently I am adding videos as I make them together with slides and problem sets. I have added a discussion forum but I can't promise to check it regularly.
The content is divided into 8 sections:
5. Enthalpy and entropy for an ideal solution
6. Hydrophobicity and entropy
7. Chemical activity and non-ideal solutions
8. The three laws of thermodynamics and the Boltzmann distribution
