Welcome to The wonderful World of Thermodynamics - ENGR 251

Course overview

Thermodynamics is, put simply, the science of energy. The study of thermodynamics is crucial in designing engines that don’t run too hot to melt, or the principles can also be used to simply explain why some things in nature happen to be the way they are. This course is structured in the following chapters:

  1. Introduction and basic concepts.
  2. Properties of Pure Substances. What did a water molecule tell the other water molecule once it started turning into ice? You’re just going through a phase.
  3. Energy Transfer by Heat and Work. Work is heat and heat is work!
  4. The First law of Thermodynamics. No, the first law of thermodynamics is not that we don’t talk about thermodynamics.
  5. The Second Law of Thermodynamics.
  6. Entropy. Once you learn about this, you can scientifically explain why your room keeps getting messier!

After you’ve completed the course, you’ll be able to explain more than just science jokes!
