Discusses the prospects and potential of geothermal utilization, paying special attention to its exploitation in the United Kingdom. (GA)

Describes a thermocouple circuit used to measure Joule heating as well as Peltier heating and cooling for a copper-Constantan metallic junction. Shows how the Seebeck effect from a thermocouple can monitor the temperature condition of a junction with regard to input power and Peltier effect. (Author/GA)

Presents an instructional approach to be used in the teaching of equilibrium processes. (CP)

This paper is concerned with the thermodynamic formulation of the Activated Complex Theory (otherwise called Transition State Theory or Absolute Rate Theory). (Author/CP)

Explains what superheated liquids are and how they are prepared. (BB)

Describes an approach for deriving expressions for thermal conductivity and dynamic viscosity which does not consider the net flow of energy or momentum across a plane. (SL)

Suggest the use of oxidation state diagrams in teaching general chemistry in order to provide a realistic presentation of thermodynamics and inorganic chemistry. (SL)

Presents a study designed to evaluate the influence of temperature on the equilibrium and the structural changes of the complexes interpreted in terms of ligand field theory. (CW)

Draws a distinction between the terms "heat and work" and "energy" in terms of the teaching of thermodynamics. Gives examples using enthalpy and constant pressure processes, free energy and spontaneity, and free energy and available mechanical energy. Concludes that there is no thermodynamic role for the terms "heat"…

Describes three examination questions which could be used in college chemistry courses. Discusses each problem and gives acceptable solutions. Problems include: "A Multi-Topic Problem for General Chemistry"; "Consumption of Air by Biuret Reagent--a Question Involving Experimental Design"; and "An Instructive Problem in Heterogeneous Equilibrium."…

Explains the phenomenon of Brownian motion, which serves as a mathematical model for random processes. Topics addressed include kinetic theory, Einstein's theory, particle displacement, and others. Points out that observations of the random course of a particle suspended in fluid led to the first accurate measurement of atomic mass. (DH)

Discusses the use of property diagrams as an instructional tool to help students understand and visualize important, complex thermodynamic relationships. Also discusses the approach used in preparing these diagrams, which were computer-generated as part of graduate students' research. (JN)

Demonstrates, with a set of definitive examples, how polymer principles can be introduced into the first undergraduate physical chemistry course in a very natural way. The intent is to encourage introduction of polymer-related material into conventional physical chemistry courses without sacrificing any rigor associated with such courses. (JN)

Presents a largely experimental approach to the concept of mixed potentials, pointing out the close parallel that exists between equilibrium potentials. Describes several important examples of mixed potentials, providing current-voltage and polarization curves and half reactions as examples. Includes a discussion of corrosion reactions and…

Considers the thermodynamic limitation to the efficiency with which light energy can be converted into work, indicating that no single chemical system converting solar energy into useful work can be very efficient. Also indicates that if solar energy is absorbed as heat for heating purposes, it is almost completely used. (JN)
