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 www.chadsprep.com/chads-gener...

Thank you so much, your video is very helpful!!! The way you explain the concept is so simple, it was really hard for me to understand the textbook and even in class because the explanation always uses complex words, the struggle of the international student:")

I am a refrigeration mechanic. Not a chemist lol. Always been fascinated by thermodynamics. Got a little lost but I think I get it. Thanks for the video.

Thank you Chad How does this relate to boze-Einstein condensate?
@ChadsPrep
@ChadsPrep 2 года назад
A boze-Einstein condensate is a gas of bosons with some interesting quantum mechanical properties that is formed at near zero Kelvin. The 3rd Law of Thermodynamics speaks more broadly of any substance being cooled to absolute zero. Assuming it adopts a pure crystalline structure it would then have zero entropy. But keep in mind this is also somewhat theoretical as we never quite achieve absolute zero Kelvin in practice (but pretty close!).

Does your general chemistry and high school chemistry playlist cover all of AP chemistry content?
@ChadsPrep
@ChadsPrep 2 года назад
Hello James. My high school playlist does not; it was designed for a standard high school chemistry class rather than an AP chemistry class. But my general chemistry playlists (old and new) definitely do. Hope this helps!

Is it appropriate to say dna has a high entropy as a molecule and as a information system?
@ChadsPrep
@ChadsPrep 2 года назад
You could say that DNA has a lot of entropy as a molecule (lots of possible microstates) but I don't how exactly to relate that to its role as an information system. And with DNA people are often more concerned with the entropy CHANGE involved in its formation or existence rather than the amount of entropy a DNA molecule has. Hope this helps!

Why did you use the symbol for ohms?
@ChadsPrep
@ChadsPrep 2 года назад
The capital omega, a greek letter, is used as the symbol for Ohms in physics but also for the number of microstates here for the calculation of entropy. It is the same Greek letter used in both places. Hope this helps!

Oops... Your formula is wrong. 2C + O2 --> 2(CO2) is not correct. You don't get 2 moles of carbon dioxide as stated in the lecture. How about 2C + O2 --> 2(CO) You do get 2 moles of carbon monoxide.
