Heat, work, energy, entropy, the laws of thermodynamics, and applications to engines, refrigeration, and chemical systems.
Core topics in Thermodynamics
- First Law
- Second Law
- Entropy
- Free Energy
- Phase Transitions
- Statistical Foundations
- Engines and Refrigeration
Why students struggle
Thermodynamics' definitions feel slippery (state functions, path-dependent quantities) until you've done enough problems to see why dU is exact and δQ isn't.
How Fennie helps
Fennie drills the distinction with problems where you choose the right thermodynamic potential before computing.
How to study Thermodynamics
- 01Master the difference between state and path functions
- 02Practice choosing the right potential (G, A, H) for each problem
- 03Use Fennie for engine-cycle problems with efficiency calculations
- 04Memorize the Maxwell relations and use them in problems
Frequently asked questions
Why does entropy feel so hard?
Because intro courses define it three different ways. Pick one (Boltzmann) and stick with it until problems work.
Is thermo necessary for chemistry?
Critical — physical chemistry is mostly thermo and quantum.
Does Fennie cover statistical mechanics?
Yes — Fennie covers partition functions, ensemble theory, and the bridge to classical thermodynamics.
