PCHEM Class Notes – Week 2

To anyone reviewing my notes: Please feel free to reach out if you need any clarification on anything I wrote! I know the cursive can get a bit sloppy at times. I try to include everything, but it’s a bit difficult to keep up with the graphs, charts, etc. at times! I try to write down the figure number for reference from our textbook.

If you want to contact me for more information/ any clarification/ to start a study group/ need talk to someone… please comment below, DM me on Instagram, or send an email by clicking this link, the icon in the top right corner, or manually typing out

CHAPTER 19 | August 26, 2019

The three laws of thermodynamics are to be covered in the next three chapters (19, 20, 21). We started with the first law, which concerns energy flow.

We covered:

  1. Work

  2. Isothermal constant

CHAPTER 19 (CONTINUED) | August 28, 2019

We covered:

  1. 1st Law of Thermodynamics

  2. Equipartition Theorem

  3. Monoatomic ideal gas

Just a note ~ everything in this course has the goal of driving things to a measurable quantity.

CHAPTER 19 (CONTINUED) | August 30, 2019

I’m a bit late to post this, but I think this is still Chapter 19. I haven’t gone through and verified this with the book, though.

We covered:

  1. Finding heat (q) with a constant volume

  2. Finding heat (q) with a constant pressure

  3. Hess’s Law

That’s all for Week 2 of PCHEM! Best of luck with your studies, and feel free to reach out to me for anything*. 🙂

(*Literally anything. If you’re panicking because you feel like you’re struggling with juggling school, work, life, relationships, friends, all with pressure to succeed and balance it all… I’ve been there as well, so have all of your fellow classmates in one way or another. It only gets easier with age and experience. Reach out for help or validation if you need it. You’re doing great. Keep it up!)
