1. Absolute Zero: Temperature & Definition
There is a limit to how cold matter can get. Learn more about what happens when the temperature gets down to absolute zero and cannot get any lower. Test your knowledge with quiz questions.
2. First Law of Thermodynamics: Law of Conservation of Energy
This video describes the first law of thermodynamics. Several examples of the application of this law are discussed. The significance of the law and its practical application are discussed as well.
3. How Does the Adiabatic Process Work? - Definition & Examples
In this lesson we will be learning about the adiabatic process. After learning the definition, we will explore examples that help demonstrate how this process occurs in nature.
4. Second Law of Thermodynamics: Entropy and Systems
In this lesson, we'll learn about the second law of thermodynamics. By studying this law, you'll understand how energy works and why we're all moving towards eventual chaos and disorder.
5. Heat Engines & Efficiency
After watching this video lesson, you will be able to explain what a heat engine is, how it works from a thermodynamic perspective, and complete some simple calculations involving the efficiency of a heat engine. A short quiz will follow.
6. Predicting the Entropy of Physical and Chemical Changes
Ever wonder why your bedroom always ends up a mess within hours of you tidying up? That is the magic of entropy. In this lesson, you'll learn why disorder is the natural state of matter and how we can predict entropy change in a physical or chemical reaction.
7. What is Entropy? - Definition, Law & Formula
In this lesson, you will learn the definition of entropy and discover how it can be applied to everyday situations. You will explore the second law of thermodynamics which is where entropy is introduced, and you will examine the formula for entropy and find out how to use it in a variety of instances.
