Explains procedures, observations, and directions for demonstrating properties of butane using reclosable plastic storage bags. States that the demonstration provides for discussion of topics such as the liquefaction of gases, heat of vaporization and refrigeration techniques, and thermodynamics. (RT)

Shows that the principles learned in the study of mass transport, thermodynamics, and kinetics associated with electrochemical systems can be applied to the transport and reaction processes taking place within a semiconductor. Describes impedance techniques and provides several graphs illustrating impedance data for diverse circuit systems. (YP)

Discusses difficulties encountered in the determination of the thermal conductivity of a gas. Provides analyses of one particular set of data. (CP)

Describes the construction of a circuit which directly measures current in a coil of superconducting wire. (CP)

Photographs of snow covered buildings are used to illustrate thermal radiation from various types of structures and the effect of insulation on heat loss. (CP)

Describes some activities for students in which the quantity of heat is measured in exercises that use inexpensive materials. (BR)

This module applies basic laws of thermodynamics to the study of the efficiency at which heat can be converted to other useful forms of energy, including heat at low temperatures. The module is divided into four major sections. Section I treats energy conversion efficiency and defines the concept of first-law efficiency, the most widely used…

This paper examines how the revolution in human thinking, with the smaller revolution in astronomy begun by Nicolus Copernicus, has plunged science educators into the new Age of Information. Examples which illustrate this development and change in human thinking (from Copernicus' time to the present) are provided from such disciplines as…

Describes an open-ended experiment involving a bioinorganic system that provides the student a direct link between thermodynamics and kinetics. It utilizes a rapid reaction technique and requires one to clearly understand the relationship of experimental observable (absorbance) to a mechanism. (GS)

Suggests the use of a colorimeter in which heat produced is related to the amperage and voltage measured. In relating the quantities, a definition for voltage can be obtained. (CP)

Presents a detailed discussion of the "Drinking Duck" toy and its use to illustrate scientific and technical issues in thermodynamics. Numerous illustrations and equations are included. (MA)

Describes an experiment giving precise results of solubility as a thermodynamics property. (SL)

Presents a mathematical and abstract approach to teaching the second law of thermodynamics in physical chemistry that is not used in any undergraduate physical chemistry text to date. (CW)

Background information, procedures used, and typical results obtained are provided for an experiment in which gas chromatography is used to prove the application of quantum symmetry restrictions in homonuclear diatomic molecules. Comparisons between experimental results and theoretical computed values show good agreement, within one to two…
