Describes a typical relaxation kinetic experiment using a sudden increase in the temperature of the system. Time involved is described as minimal and the approach as quicker, more accurate, sensitive, and producing simultaneous determination of several thermodynamic parameters. (Author/SA)

Describes the use of computer-assisted graphical displays in experiments to determine the order and activation energy for a chemical reaction. (MLH)

Teaching procedures of Project Physics Unit 3 are presented to help teachers make effective use of learning materials. Unit contents are discussed in connection with teaching aid perspective, multi-media schedules, schedule blocks, and resource charts. Brief analyses are made for transparencies, 16mm films, and reader articles. Included is…

Fundamentals of shipboard machinery, equipment, and engineering plants are presented in this text prepared for engineering officers. A general description is included of the development of naval ships, ship design and construction, stability and buoyancy, and damage and casualty control. Engineering theories are explained on the background of ship…

Describes an analog computer which serves as a visual aid that calculates the amounts of all substances in an equilibrium mixture as well as during the reaction. (MLH)

Describes a short undergraduate experiment which helps in explaining the concept of entropy and in illustrating the second law of thermodynamics. (GA)

This is part of a series of 42 Calculus Based Physics (CBP) modules totaling about 1,000 pages. The modules include study guides, practice tests, and mastery tests for a full-year individualized course in calculus-based physics based on the Personalized System of Instruction (PSI). The units are not intended to be used without outside materials;…

Presented are two demonstrations; "Heat of Solution and Colligative Properties: An Illustration of Enthalpy and Entropy," and "A Vapor Pressure Demonstration." Included are lists of materials and experimental procedures. Apparatus needed are illustrated. (CW)

Suggests a change in physical chemistry courses to use a slightly more complicated but significantly more useful generalization of the simple freezing point depression law. Lists reasons for the change and presents the treatment of solid-liquid equilibria where solid-solution is allowed. Provides a mathematical treatment. (MVL)

The effect of color on heat absorption ability is demonstrated using different color copper disks on a snow covered surface. (CP)

Attempts to provide an intuitive understanding of steady state kinetics. Discusses the meaning of steady state and uses free energy profiles to illustrate and follow complex kinetic and thermodynamic relationships. Provides examples with explanations. (MVL)

Six 12-year-old students were followed during an eight-month course using "Energy and Change" curricular materials, which introduce ideas related to the Second Law of Thermodynamics through an abstract picture language. Concludes that students had higher levels of generalization in their explanations of physical, chemical, and biological…

Vogtle Electric Generating Plant operated by Southern Nuclear Operating Company, a subsidiary of Southern Company, has found itself at a decision point. Vogtle depends on their natural draft cooling towers to remove heat from the power cycle. Depending on the efficiency of the towers, the cycle can realize more or less power output. The efficiency…

This publication is a Mechanical Engineering Laboratory Manual designed to be used by technical institute students in Mechanical Engineering Technology Programs. The experiments are introductory in nature and embrace the fields of applied thermodynamics, fluid mechanics, refrigeration, heat transfer and basic instrumentation. There are 20…
