Josiah Willard Gibbs developed a framework for understanding how mixtures of substances behave at equilibrium. Krishna Choudhary and Lester Nare introduce his work on heterogeneous substances and explain why chemical thermodynamics matters when different materials and phases interact.
- 01
Gibbs extended thermodynamic reasoning to systems containing different substances.
- 02
Equilibrium provides a way to describe the behavior of interacting materials and phases.

17:55Uh, another physics note in 1876, the founding of chemical thermodynamics. >> Yeah, this was um huge. This is um Josea Willard Gibbs from the Gibbs Ensemble. He wrote this thing called the on the equilibrium of heterogeneous substances. Um he rigorously applied thermodynamics to chemical reactions and he gives us something that is a full picture of statistical mechanics. This is really where statistical mechanics, classical statistical mechanics ends. It starts with the Maxwell distribution and entropy and all those classic things by Carno and things like that in Europe.
18:35Gibbs is where he starts talking about phases of matter. What if I have two different substances within my equilibrium? How does equilibrium get reached? This was at Yale University and um >> Boo but yeah but but okay >> but okay this he's he's one he's really the the first guy to bring theoretical physics >> to the forefront in America. >> Go Bulldogs. >> Yeah.
