Five brief items are discussed. They include (1) preservation of reactive ions in solid solution, (2) the molecular partition function, (3) purification of methoxychlor, (4) a kinetics experiment, and (5) determining molecular weights of acids. (RWH)

This simple example demonstrates the physical significance of similarity solutions and the utility of dimensional and asymptotic analysis of partial differential equations. A procedure to determine the existence of similarity solutions is proposed and subsequently applied to transient constant-flux heat transfer. Short-time expressions follow from…

Describes how to teach about "heat" and suggests do's and don'ts concerning the terminology and ideas which surround the concept of heat, in order to avoid student confusion and misconception. (BR)

A technique is described for the generation of perspective views of three-dimensional models using computer graphics. The technique is applied to models of familiar thermodynamic phase diagrams and the results are presented for the ideal gas and van der Waals equations of state as well as the properties of liquid water and steam from the Steam…

Reviews the history of selected topics in physical chemistry, including kinetics, thermodynamics, quantum chemistry, and nuclear chemistry. (MLH)

Reports on technological advancements in the fields of solar collectors, thermal storage systems, and solar heating and cooling systems. Diagrams aid in the understanding of the thermodynamics of the systems. (CP)

Presented here are improvements in the original design of an introductory statistical thermodynamics experiment with the result that heat capacities of metals are routinely obtained within ten percent of literature values. (BB)

Introduces a pictorial, intuitive approach that allows the teaching of thermodynamics equilibrium in an introductory college physics course. (GA)

Lists several ideas for experiments for the amateur scientist to try or design. The list covers a wide range of topics; sound, mechanics, thermodynamics, fluids, optics, and electrostatics. (GA)

Describes the relationship existing between coefficient of performance (COP) and energy efficiency ratio (EER) in air conditioning units and introduces new efficiency parameters measured relative to the energy extracted from the primary energy source. (SL)

Discusses the information-theoretic statistical mechanics of a system in contact with heat reservoir. (SL)

Presents a simple model whereby the work per cycle done on an external agent, and a sand reservoir, by a reversible heat engine can be analyzed explicitly. (Author/SL)
