the Second Law of Thermodynamics!
|Entropy and the second law of thermodynamics|
|The second law of thermodynamics is a tendency|
|Obstructions to the secondlaw make life possible|
|The second law of thermodynamics and evolution|
|Entropy and Gibbs free energy, DG = DH -TDS|
These are five big ideas involving the second law of thermo. Questions about them came from readers of http://www.secondlaw.com. However, that Web site already has so many pages that this new site was written.
We’ll be talking about them in relaxed fashion but with the goal of developing a
sound qualitative understanding. (Equations will be minimized, except in the last section
about the Gibbs function.) No reader asked about two topics, so each is mostly
independent. Thus, there are some paragraphs that are repeated.
Students: If you're in a time bind or an exam is coming up, read http://www.entropysite.com/students_approach.html for a shorter approach to understanding the second law and entropy.

The Encyclopedia Britannica has not only given this site an Internet Guide Award but is allowing a direct search link to its great encyclopedia. Thus, in addition to going on to much more complex aspects of the second law after reading this site, you can also access the entire span of knowledge in the Britannica -- all of science, the humanities, and practical matters in the world
