Describes an oscillating chemical reaction, and discusses numerous parallels to it in research, such as in fibrillation of the heart, body-clock rhythms of animals and plants, the self-assembly of multicellular organisms, and certain stripes in volcanic rock. (GA)

Discusses two different uses of information theory in chemistry to present entropy and chemical structure analysis. (GA)

Presents a detailed analysis of the thermodynamic equation dE = TdS - PdV to illustrate how chemistry teachers may present chemical potential by a route free from the terrors of partial derivatives. (MR)

Describes an experiment simulating heat transfer and overall energy loss in upper layers of soil surfaces. (SL)

Discussed are how the thermal vibrations of a solid are described in terms of lattice waves, how these waves interact with other waves, or with themselves, and how one is led from such a description in terms of waves to the concept of a phonon. (Author/MA)

Discusses proposed fallacies in basic thermodynamic statements often presented as absolute truths. (SL)

Presents a consistent approach to the introduction of the mole in teaching kinetic theory and thermodynamics of ideal and real gases. (SL)

Contains contributed suggestions for laboratory equipment, chemistry activities, and explanations of chemical reactions. (CP)

Shows how the thermodynamic condition for equilibrium in an isolated system can be derived by the application of Boltzmann's law to a simple physical system. States that this derivation could be included in an introductory course on chemical equilibrium to help prepare students for a statistical mechanical treatment presented in the curriculum.…

Discusses theory of thermodynamics of the equilibrium in solution and dissociation-dimerization kinetics. Describes experimental procedure including determination of molar absorptivity and equilibrium constant, reaction enthalpy, and kinetics of the dissociation-dimerization reaction. (JM)

Procedures for demonstrating thermodynamic changes, kinetics and reaction mechanisms, equilibrium, and LeChatelier's principle are presented. The only materials needed for these demonstrations are beakers, water, assorted wooden blocks of varying thickness, assorted rubber tubing, and a sponge. The concepts illustrated in each demonstration are…

Discusses the values presented in various handbooks for the boiling point and heat of vaporization of sulfuric acid, noting discrepencies. Analyzes various approaches to data presentation, discussing the data on sulfuric acid in light of the Trouton constant. Points out the need for a more critical use of tables. (JM)

Thermal imagers are able to form images of scenes because the thermal emissions from different elements of the scene as viewed by the imager differ from each other. Several demonstrations with a thermal imager and a discussion of Count Rumford's 1807 experiment are presented. (JM)

Describes a simulated laboratory research project in which the thermodynamic and kinetic aspects of ammonia synthesis are simulated on a computer. (MLH)
