About this course
This course works through the ideas that govern every engine, fridge and chemical reaction: energy conservation, entropy and the direction of change, and what makes a process reversible or wasteful. You'll answer multiple-choice questions on the zeroth through third laws, work and heat, internal energy and enthalpy, ideal gas processes, Carnot and power cycles, refrigeration, and phase change. It's for engineering and science students, anyone revising for an exam, and curious readers who want the real version rather than the slogan.
Why practice thermodynamics
Thermodynamics is where confident misconceptions live longest — heat confused with temperature, entropy treated as mess, a sign convention flipped halfway through a problem. Answering questions forces you to commit to a system boundary and a direction, and the worked explanation catches the assumption you didn't notice you were making.
How this course works
- Short MCQ sessions you can finish in a coffee break
- Every answer comes with a worked explanation and why the distractors are tempting
- Scenario questions built on real engines, fridges and everyday processes
- Difficulty ramps from definitions to full multi-step cycle analysis
What you'll walk away with
A dependable feel for what the first and second laws actually forbid, the ability to set up a system and sign convention without second-guessing, and enough repetition that cycle efficiency problems stop being formula-hunting.
