Mechanical theories are presented in this unit of the Project Physics text for senior high students. Collisions, Newton's laws, isolated systems, and Leibniz' concept are discussed, leading to conservation of mass and momentum. Energy conservation is analyzed in terms of mechanical energy, heat energy, steam engines, Watt's engine, Joule's…

Performance objectives are stated for this secondary school instructional unit concerned with aspects of physical chemistry, involving the physical properties of matter, and laws and theories regarding chemical interaction. Lists of films and state-adopted and other texts are presented. Included are enrollment guidelines; an outline summarizing…

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)

Discusses the principle of nonisothermal kinetics and some of the factors involved in such reactions, especially when considering the reliability of the kinetic parameters, compared to those of isothermal conditions. (GA)

Describes a machine which demonstrates the statistical bases of chemical equilibrium, and in doing so conveys insight into the connections among statistical mechanics, quantum mechanics, Maxwell Boltzmann statistics, statistical thermodynamics, and transition state theory. (GA)

Describes an experiment, in solid-state physics, for measuring the Shubnikov-de Haas oscillations in indium antimonide. It also provides an introduction to low-temperature techniques and to cryomagnetic systems. (Author/GA)

This article describes the undergraduate ChE thermodynamics course at Drexel University and the reasons for incorporating a series of laboratory experiments into the course. Included is a list of lecture topics and a description of each of the experiments. (BB)

Explores the problem of how to determine standards of performance for energy conversion processes. Argues against infinitely slow reversible processes as standards, and explores simple and faster alternative processes. (Author/GA)

Describes a simple chemistry laboratory experiment which allows students to calculate thermodynamic values. (SL)

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…

Describes how microcomputers can perform very demanding/large-scale physics calculations at speeds not much slower than those of modern, full-size computers. Among the examples provided are a Monte Carlo simulation of the three-dimensional Ising model and a program (for the Apple microcomputer) using the time-independent Schrodinger Equation. (JN)
