A discussion of entropy that focuses on explaining entropy, how it applies to the second law of thermodynamics, and real-life observations of the existence of entropy.

An experiment to investigate the thermal properties of rubber by studying its behavior in different scenarios. A discussion of how entropy explains what is observed is provided.

A nice juxtaposition of endo- and exothermic reactions. Outlines two demonstrations. Barium hydroxide, sodium acetate, ammonium nitrate, ammonia.

With an overview of topics related to chemical equilibrium, this site provides a foundation to a study of thermodynamics and entropy. Other topics covered include standard entropy, gases, and more.

With an overview of topics related to chemical equilibrium, this site provides a foundation to a study of thermodynamics and entropy. The specific topic addressed is effect of temperature, volume, and concentration on the entropy.

With an overview of topics related to chemical equilibrium, this site provides a foundation to a study of thermodynamics and entropy. The subject, absolute entropies, is discussed in addition to the third law of thermodynamics, phase...

At the end of this tutorial, the learner will understand the concepts of entropy and negentropy and will understand that systems gradually move towards entropy unless additional energy is introduced to them. It is 2 of 3 in the series...

If you stick water in the freezer, it will take a few hours to freeze into ice. How is it, then, that cold packs go from room temperature to near freezing in mere seconds? John Pollard details the chemistry of the cold pack, shedding...

Understand chemical reactions by learning about enthalpy and entropy.

Explains entropy in a system and how it is measured.

A colorful presentation of precipitation reactions with many diagrams and explanations. Very high level.

In this interactive unit on thermodynamics, you'll learn why heat flows the way it does and how that flow of thermal energy can be put to good use in your daily life.

Students use a watt meter to measure energy input into a hot plate or hot pot used to heat water. The theoretical amount of energy required to raise the water by the measure temperature change is calculated and compared to the electrical...

This lesson will explain how to identify changes in entropy and provide examples of entropy change.

A detailed discussion of solubility as a function of Enthalpy and Entropy. Goes way beyond the standard solubility discussion.
