Temperature and Heat
Seems OK

The Kinetic Theory of Gases

 * 1) Not-to-worry I make this mistake during lecture all the time: $$\bar v=\sqrt{\tfrac 8\pi\tfrac{RT}{M}}$$ is the average speed, not the average velocity --Guy vandegrift Noto_Emoji_Oreo_1f921.svg (discuss • contribs) 01:54, 2 February 2018 (UTC)

The First Law of Thermodynamics
Seems OK

The Second Law of Thermodynamics

 * 1) " $$\oint \tfrac{dQ}{T}$$ for any COMPLETE cyclic process. "  ... What is an INCOMPLETE cyclic process? (... or maybe this is something I should know about?)
 * 2) " $$\Delta S \ge 0$$ describes the change of entropy of a closed system under any REVERSIBLE process "  Why must it be reversible?... (or maybe there is a way to  decrease  entropy in a closed system if the process is irreversible???)

Where should I put all these equation sheets?
I am moving this discussion to Talk:OpenStax equations--Guy vandegrift (discuss • contribs) 20:32, 28 February 2018 (UTC)
