Entropy Teacher Resources

Students define thermal equilibrium. They distinguish between internal energy and heat. Students describe how the quantity of heat that enters or leaves a substance is measured.

In this science activity, learners are using the laws of thermodynamics and a basic knowledge to fill in the sentences with the correct words.

Students investigate the laws of thermodynamics. They observe demonstrations of each law, read a summary, and analyze how pizza demonstrates the laws of thermodynamics.

Students investigate the concept of molecular structure. They describe the behavior of simulated molecules and identify any dislocations in crystalline structures. They also define various related vocabulary words and use them in...

Students study how to complete thermochemical equations.  In this equation lesson students learn how to manipulate equations to calculate energy changes and reactions.

An explanation to prove that entropy, labeled as S, is a valid state variable. [15:38]

Do you know why heat increases entropy? In this video, students can explore entropy and its ability to do work. [7:01]

Using a reversible system to clarify the definition of entropy in thermodynamics. [15:38]

An introduction to entropy and its relationships to various states for a system. [7:27]

By the end of this section, you will be able to define entropy, calculate the increase of entropy in a system with reversible and irreversible processes, explain the expected fate of the universe in entropic terms, and calculate the...

As part of the General Chemistry Virtual Textbook, this site examines a variety of topics related to entropy. Other topics covered include how thermal energy is stored in molecules, quantum states, microstates and energy spreading, and...

With an overview of topics related to chemical energetics, this site provides a foundation to a study of thermodynamics and its relation to entropy. Information on the topic ranges from reversible and irreversible changes to standard...

[Free Registration/Login may be required to access all resource tools.] After identifying the two driving forces behind all chemical reactions and physical processes, students investigate entropy, and predict whether the entropy change...

An explanation showing the differences between microstates and macrostates emphasizing that entropy is defined for a system and not different microstates. [8:56]

Explanation of how entropy relates to the number of states a system can take on. [28:26]

Learn that the entropy of the universe is constantly increasing according to the second law of thermodynamics in this video. [8:32]

With an overview of topics related to chemical equilibrium, this site provides a foundation to a study of thermodynamics and its relation to entropy. Other topics covered include entropy and disorder, absolute entropies, and more.

Introduction to entropy, and how entropy relates to the number of possible states for a system. [7:26]

Entropy is simply the dispersion of matter or energy. Paul Andersen begins with a series of video that show the natural direction of processes. According to the second law of thermodynamics the entropy may never decrease in a closed...

This lesson will introduce the second law of thermodynamics and define the term entropy, providing examples of entropy.

Understand the 2nd Law of Thermodynamics. Disorder is a pretty big deal in the universe and that makes it a pretty big deal in chemistry - it's such a big deal that scientists have a special name for it: entropy. In chemistry, entropy is...

Long video explaining why entropy is a measure of the number of states a system can take on. [28:26]

Introduces second law of thermodynamics. A discussion of entropy change in terms of heat and microstates. [19:15]
