Chad continues the chapter on Thermodynamics with a lesson on Entropy. First an entropy definition is provided according to Boltzmann's Equation which examines entropy from the molecular perspective and relates it to the number of possible microstates in the system. Next, a variety of factors which affect entropy are discussed including phase, temperature, volume, and the number of particles. Finally, these factors are used to examine entropy changes and to come up with a method of predicting the sign of Delta S for a reaction or process.

I've embedded this playlist as a course on my website with all the lessons organized by chapter in a collapsible menu and much of the content from the study guide included on the page. Check this lesson out at https://www.chadsprep.com/chads-gener...
