Hello, Thank you for posting this video! My thermodynamics textbook is written by Gaskell and often times the book completely looses me and I end up finding it very difficult to understand as I read ahead cluelessly. Your video is VERY clear and helps a student like me finally understand the material. A big THANK YOU!
Great Presentation! Minute 8-9 you are showing that the probability of the three types of bonds equals to one by substitution of X(b) with 1-X(a). You can just easily say that X(a)^2+2X(a)X(b)+X(b)^2=[(X(a)+X(b)]^2=1. Thanks again!
Gaskell's a classic, one of the old school. The regular solution model is mathematically quite arduous - not hard per se, just a long derivation. But its very rewarding in unlocking phase diagrams, computational thermodynamics and ultimately, alloy design by computational materials engineering. So the $100m US NSF Materials Genome Initiative, for example, largely springs from this. So: let me encourage you to keep going! The end is worth it! [And, thank you for the comment: it encourages me]
I'm so thank full for your video, but I suggested you in explanation to describe what the meaning of w or H or G, for example G is gibbs energt (kJ/mol) and etc.
Good comment! But, this is intended for people in their 4th week at university! I'm trying not to make it any more complex than I absolutely have to to make the point that Gibbs Energy curves can be constructed mathematically and then related to phase diagrams. Colleagues then repeat this in our second year class, more slowly and carefully, to elaborate the Bragg-Williams model properly. i.e. this is 'spiral 1' in a programme - 'spirals 2 and 3' expand and deepen the ideas. But, thanks!
I have a suggestion concerning enthalpy of mixing: it is quite interesting to underline the 2 main hypotheses of the Bragg-Williams model: 1- after the first draw of an A atom, the probability to draw a second A atom is xA only if interactions between A and B are sufficiently weak, otherwise there is a bias. 2- secondly, in your derivation, you consider that pure A and B have the same coordinence number z as in the A-B solution, it is a way to introduce the concept of state of reference.
Interesting lecture professor. @Javed: I think the professor mentions at Wh0, formation of "partial " solution of both is possible as the graph suggests at around 44 min. I hope this helps you.
Great lecture but a little correction: Entropy was introduced by Boltzmann, and k is Boltzmann's constant, probably a slip of the tongue. Thanks for such an effort online...

Excellent explanation. Thank you so much!!!

Excellent and very accessible derivation and explanation of the regular solution model . THANK YOU.

hello from Turkey.you are a really good teacher, thank you very much:))
Dear do u know about istenbul university?
Its not the planks constant its the boltzsman constant
Great lecture but a little correction: Entropy was introduced by Boltzmann, and k is Boltzmann's constant, probably a slip of the tongue. Thanks for such an effort online...
can we have lectures on complete thermodynamics
In your last part around 44min you state that when Wh>0 we get an intermetallic system, shouldnt it be when Wh is
nice lacture according to syllabus .. thanks sir......
have you some application of this theory?
My brother loves you
Dear Prof.i love your video lecture on thermodynamics of solution, is there any way i can get the full video lecture series?
is this related to Flory-Huggins theory? :/
Very nice video, simple and sweet, but sorry, k is boltzmann constant
Sir give this chapter notes pdf
I love thermodynamics...
zet hahahahaha
