Summary
Thermodynamics tracks heat, work, and energy — what can spontaneously happen and what can't.
Energy is conserved (1st law). Entropy of an isolated system tends to increase (2nd law) — gives time an arrow.
- Engines can't be 100% efficient.
- Absolute zero unreachable in finite steps (3rd law).
