Lesson #3259 - Adiabatic

Thermodynamics! Rarely a comfort except in its general consistency.

Quick side note - it was announced yesterday that I was named to AIChE's 35 under 35, and that's an honor that certainly wouldn't have happened if I hadn't been making science and engineering comics, which wouldn't have happened without STW and PhD Unknown. So my sincere thank you to all of you who helped lead to such an honor being possible!
