COURSE DESCRIPTION
This course provides an introduction to the most powerful engineering principles you will ever learn - Thermodynamics: the science of transferring energy from one place or form to another place or form. We will introduce the tools you need to analyze energy systems from solar panels, to engines, to insulated coffee mugs. More specifically, we will cover the topics of mass and energy conservation principles; first law analysis of control mass and control volume systems; properties and behavior of pure substances; and applications to thermodynamic systems operating at steady state conditions.
COURSE FORMAT
The class consists of lecture videos, which average 8 to 12 minutes in length. The videos include integrated In-Video Quiz questions. There are also quizzes at the end of each section, which include problems to practice your analytical skills that are not part of video lectures. There are no exams.
GRADING POLICY
Each question is worth 1 point. A correct answer is worth +1 point. An incorrect answer is worth 0 points. There is no partial credit. You can attempt each quiz up to three times every 8 hours, with an unlimited number of total attempts. The number of questions that need to be answered correctly to pass are displayed at the beginning of each quiz. Following the Mastery Learning model, students must pass all 8 practice quizzes with a score of 80% or higher in order to complete the course.
ESTIMATED WORKLOAD
If you follow the suggested deadlines, lectures and quizzes will each take approximately ~3 hours per week each, for a total of ~6 hours per week.
TARGET AUDIENCE
Basic undergraduate engineering or science student.
FREQUENTLY ASKED QUESTIONS
- What are the prerequisites for taking this course?
An introductory background (high school or first year college level) in chemistry, physics, and calculus will help you be successful in this class.
-What will this class prepare me for in the academic world?
Thermodynamics is a prerequisite for many follow-on courses, like heat transfer, internal combustion engines, propulsion, and gas dynamics, to name a few.
-What will this class prepare me for in the real world?
Energy is one of the top challenges we face as a global society. Energy demands are deeply tied to the other major challenges of clean water, health, food resources, and poverty. Understanding how energy systems work is key to understanding how to meet all these needs around the world. Because energy demands are only increasing, this course also provides the foundation for many rewarding professional careers....

1In this module, we frame the context of energy and power supply and demand around the world. You will learn that understanding and correctly using units are critical skills for successfully analyzing energy systems. It is also important to be able to identify and categorize systems as “open” or “closed” and “steady state” or “transient”. Thermodynamics is a topic that is very notation intense, but the notation is very helpful as a check on our assumptions and our mathematics. Additionally, in this module we will refresh our understanding of some common thermodynamic properties....

2In this module, we will get started with the fundamental definitions for energy transfer, including the definitions of work transfer and heat transfer. We will also show (by example) how state diagrams are valuable for explaining energy transfer processes. Then, we have all the tools we need to define the 1st Law of Thermodynamics also called the Conservation of Energy. Your second assignment will emphasize these principles and skills....

3In this module, we introduce our first abstract concepts of thermodynamics properties – including the specific heats, internal energy, and enthalpy. It will take some time for you to become familiar with what these properties represent and how we use these properties. For example, internal energy and enthalpy are related to temperature and pressure, but they are two distinct thermodynamic properties. One of the hardest concepts of thermodynamics is relating the independent thermodynamic properties to each other. We have to become experts at these state relations in order to be successful in our analysis of energy systems. There are several common approximations, including the ideal gas model, which we will use in this class. The key to determining thermodynamic properties is practice, practice, practice! Do as many examples as you can....

Great practical information to thermodynamical processes and machines with many calculated examples. A bit light on the fundamental definitions, like entropy, but very good for hands-on work.

Great intro course to thermodynamics. A follow up course with more advanced topics (2nd law, exergy etc.) would definitely be useful. A course at the graduate level would be very welcome!
