Entropy  
These processes are shown in reverse. The situations shown are so highly improbable that we would not expect to observe them in nature.

Exploding Soap Bubbles: Hydrogen + Oxygen  
A series of three videos shows that as the ratio of oxygen to hydrogen in soap bubbles increases, the explosions that occur when the bubbles are ignited get louder. (The fact that with an excess of oxygen the explosions would become softer again is not shown.) Each video is repeated with no voice-over so that only the sounds of the explosions are heard. Five still images are provided to show the stoichiometry on the molecular scale. The videos are intended to be shown in order beginning with Hydrogen Alone and ending with hydrogen plus more oxygen.

Thermodynamics : PredictEntropyChange (10 Variations)
For each of the following processes, indicate whether you expect the entropy change of the system to be positive or negative.
Thermodynamics
Thermodynamics : CompareEntropyQual (16 Variations)
Indicate which substance in each of the following pairs of substances you expect to have higher entropy. Assume that you have a mole of each substance and all substances are at the same temperature.

Thermodynamics : ProbabilityEnergyDist (23 Variations)
Consider a system that has two indistinguishable molecules that can occupy three different energy levels (having energies of 1kJ, 2kJ and 3kJ, respectively). What is the probability that the molecules will have a total energy of 2 kJ?

The Correlation of Binary Acid Strengths with Molecular Properties in First-Year Chemistry  Travis D. Fridgen
This article replaces contradictory explanations for the strengths of different binary acids in first-year chemistry textbooks with a single explanation that uses a BornHaber cycle involving homolyic bond dissociation energies, electron affinities, and ion solvation enthalpies to rationalize trends in the strengths of all binary acids.

Undergraduates' Understanding of Entropy  Arnd H. Jungermann
Szbilir and Bennett carried out an extensive investigation on undergraduates understanding of entropy. Though I agree in general with their statements that orderdisorder arguments form a misleading entropy concept, I would like to make some comments with regard to a certain part of their online supplement.

Using Graphs of Gibbs Energy versus Temperature in General Chemistry Discussions of Phase Changes and Colligative Properties  Robert M. Hanson, Patrick Riley, Jeff Schwinefus, and Paul J. Fischer
The use of qualitative graphs of Gibbs energy versus temperature is described in the context of chemical demonstrations involving phase changes and colligative properties at the general chemistry level.
