Investigated the problems chemistry majors have with learning distillation concepts in traditional chemistry laboratory courses. Reports that students take the generalized concepts at face value, construct decontextualized concepts for distillation, and cannot interpret their observations or make reasoned decisions based on the theoretical…

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…

Described is an experiment designed to provide an experimental basis for a unifying point of view (utilizing theoretical framework and chemistry laboratory experiments) for physical chemistry students. Three experiments are described: phase equilibrium, chemical equilibrium, and a test of the third law of thermodynamics. (Author/DS)

Describes several experiments using the techniques of thermal analysis and thermometric titrimetry. Defines thermal analysis and several recent branches of the technique. Notes most of the experiments use simple equipment and standard laboratory techniques. (MVL)

Recommends determining molecular weights of liquids by use of a thermocouple. Utilizing a mathematical gas equation, the molecular weight can be determined from the measurement of the vapor temperature upon complete evaporation. Lists benefits as reduced time and cost, and improved safety factors. (ML)

Describes an apparatus capable of measuring absolute temperatures of a tungsten filament bulb up to normal running temperature and measuring Botzmann's constant to an accuracy of a few percent. Shows that electrical noise techniques are convenient to demonstrate how the concept of temperature is related to the micro- and macroscopic world. (CW)

Introduces three physics experiments for high school and college classes. Topics include measuring the ratio of heat capacities using a microcomputer and a glass syringe, producing large electric sparks using a variation of a Leyden bucket, and observing transmission line behavior using television signals. Includes descriptions of materials and…

This course in chemistry for energy technology is one of 16 courses in the Energy Technology Series developed for an Energy Conservation-and-Use Technology curriculum. Intended for use in two-year postsecondary technical institutions to prepare technicians for employment, the courses are also useful in industry for updating employees in…

Designed for individualized use in an applied physics course in postsecondary vocational-technical education, this series of twenty-three learning modules is equivalent to the content of two quarters of a five-credit hour class in electrical technology, electronic service technology, electronic engineering technology, or electromechanical…
