Uses reversible electrochemical cells near equilibrium to study basic thermodynamic concepts such as maximum work and free energy. Selects sealed, miniature, commercial cells to obtain accurate measurement of enthalpy, entropy, and Gibbs free energy. (MVL)

Describes a laboratory exercise in which acid dissociation constants and molecular weights are extracted from sample data and the sample is identified. Emphasizes accurate volumetric work while bringing to practice the concepts of acid-base equilibria, activity coefficients, and thermodynamic constants. (CW)

Presents a laboratory experiment which determines critical temperature and density of carbon dioxide. Discusses critical point and provides equations to estimate liquid volume fraction. Analyzes experimental results in terms of variables. (JM)

Briefly describes the application of thermodynamics (system at equilibrium) to the study of the extraction of metals from their oxides (dynamic situation). It is more relevant to study the temperature variation of the equilibrium constants of the reaction than to study the free energy approach. (Author/SK)

Describes a resonance apparatus for the measurement of Cp/Cv for different gases. In the apparatus a magnetically supported piston in a vertical cylindrical glass tube containing the gas is forced into oscillation by means of a standard audio signal generator. (Author/GA)

Describes two experiments designed to provide concepts on the difference between heat and temperature and also bond energy. Investigates both a neutralization experiment and a ligation experiment. Notes inexpensive chemicals are used along with simple equipment. Discusses the sharing of lab results for a single class value. (MVL)

Presents the work of Newton in thermometry and argues that it is a quite distinguished work in this area and exemplifies Newton's brilliance as an experimenter. (PR)

Research offers important suggestions concerning science curriculum design, and real-time data collection technology offers great opportunities. This paper discusses how recent increases in understanding the nature of the learner and the process of instruction combined with recent advances in technology might lead to improved science instruction.…

Describes a series of experiments (intended to approximate the research experience) investigating the reaction of ferrocenylmethylation with aniline. Students carry out reactions in nitrogen atmosphere, identify products by nuclear magnetic resonance spectroscopy and propose mechanisms and structures for reactions. Gives procedures for each…

This unit on chemical energetics is one of 10 first year units produced by the Independent Learning Project for Advanced Chemistry (ILPAC). The unit, which consists of two levels, provides a clear yet detailed and thorough introduction to the topic. Level one extends ideas from previous courses, introduces and emphasizes the importance of Hess'…

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…

A time-sharing FORTRAN program is described. It was created to allow a student to design and perform classical thermodynamic experiments on three models of a working substance. One goal was to develop a simulation which gave the student maximum freedom and responsibility in the design of the experiment and provided only the primary experimental…

Discusses the benefits of thermochromic transformations for studying thermodynamic properties. Describes an experiment that uses a commercially available dye, attains equilibrium rapidly, employs a simple, single-beam spectrophotometer, and is suitable for both physical chemistry and introductory chemistry laboratories. (TW)

This publication is a laboratory study guide designed for mechanical engineering students. All of the experiments (with the exception of experiment No. 1) contained in the Mechanical Engineering Laboratory Manual have been included in this guide. Brief theoretical backgrounds, examples and their solutions, charts, graphs, illustrations, and…

Describes a simple thermodynamics experiment recommended for use in beginning chemical engineering laboratory courses. Outlines the theory behind the experiment, which determines the specific heat of a liquid. Discusses the construction, operation, and maintenance of the apparatus involved, along with the experimental procedure. (TW)
