Engineer's Notebook
Thermodynamics
How heat and work move energy in and out of a system, and how gases respond. Each topic opens with its formula, then a demo you can change.
1 · Gases
| 1.1 | Ideal gas law | pV = nRT |
|---|---|---|
| 1.2 | First law | ΔU = Q − W |
2 · Heat transfer
| 2.1 | Conduction | q = −k dT/dx |
