Errata in Volume 2 chapter summaries

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 (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. "$\Delta S\geq 0$ 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)
