18.2 Entropy | General Chemistry

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.

About to take my final in Physical Chemistry, this helped a ton!

[gavindiff]

thank so so much i was a little confused when my teaher went over this but I'm starting to get it! now I just gotta do some book problems and go to office hours and ill be golden.

I am a botany student and it helps me alot for understanding the concept of water potential...

[jazminrojas]

Makes so much more sense, thanks Chad!!

[kimchi]

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.

Do you have a Masters in Chemistry and Physics.Cheers Ricky

As I set yet another curve and classmates ask me what my secret is, I coolly respond, "it's Chad."

Is it appropriate to say dna has a high entropy as a molecule and as a information system?

[estimatingonediscoveringthree]

Thank you Chad
How does this relate to boze-Einstein condensate?

[garysampson]

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.

Does your general chemistry and high school chemistry playlist cover all of AP chemistry content?

This comment is to let you know you’re awesome 😅
