I’m aggregating here some useful links for the Thermo courses. You might also want to check out the posts tagged with “Thermo” and “Links”.

  1. The entropy function S(E,V,N_{i})

    Aatish Bhatia’s great article: What the Dalai Lama can teach us about temperatures below absolute zero.

  2. Temperature

    Veritassium folks have two videos: Misconceptions about temperature, and Can humans really feel temperature?.

  3. Phase transformations

    Freezing of supercooled water: Here’s a demo.

    Water expands on freezing by about 9% by volume (which translates, rougly, to about 3% along each dimension); this is really huge. How huge? Here’s a demo.

    You can freeze water by boiling a solution of water and acetone. Confused? Here’s a demo. By the way, you can also freeze water by boiling it at low pressure, but I am not able to find a video which does this.

    Tin pest is a fantastic phenomenon, and it looks spooky in this time-lapse video.

    Precipitation: Top 7 crystal growth experiments

    This video has all kinds of things about tin: tin pest, tin whiskers, crystallization from a solution through electrolysis. Very informative, and visually stunning.

  4. Phase Diagrams

    The {\rm Al}_{2}{\rm O}_{3} - {\rm SiO}_{2} system [Wikimedia Commons].

    The Ni-Al system [Wikimedia Commons].

    The Ag-Pt system. [from this page by Prof. W.H. Warnes at Oregon State University.]

    At the San Jose State University, Prof. Guna Selvaduray has made available quite a few phase diagrams.
