Ch 3: Fundamentals of Thermodynamics

About This Chapter

Watch thermodynamics video lessons and learn definitions of the types of energy, the laws of thermodynamics and more. These video lessons are short and engaging and make learning easy!

Fundamentals of Thermodynamics - Chapter Summary and Learning Objectives

What is energy? How does it affect you, nature and the world around us? Our lessons on thermodynamics will help you understand the answers to these questions. What is thermodynamics even about? We have lessons that cover its first and second laws to make this concept stick in your head. Discover the laws of conservation and entropy in these lessons.

You can also dive right in with our lesson that explains the basics of energy. Discover what energy is and why it's so significant. Then watch our lesson that goes into kinetic energy and teaches you about the different energy types. Additionally, see how these types of energy are related. You can watch lessons that will cover the definitions of individual types of energy, such as mechanical, thermal, radiant, chemical, electric and nuclear. Also take a look at our lesson that discusses energy and life to discover how energy is transformed and used in living organisms.

What is the relationship between heat and temperature? You'll find out after watching our lessons. You'll also find out how to calculate the heat capacity of substances and learn how to describe the unique characteristics of heat in different substances. Don't forget to watch our video that will help you learn to use diagrams to model changes in heat and temperature.

Energy can be a fun topic, as you will see when you're watching our videos. It has many interesting elements, and you'll learn all about them as you watch. Enjoy our videos and thanks for watching!
