Unlike many elementary presentations on heat, this monograph is not restricted to explaining thermal behavior in only macroscopic terms, but also developes the relationships between thermal properties and atomic behavior. "It relies at the start on intuition about heat at the macroscopic level. Familiarity with the particle model of mechanics,…

Shows that the entropy change during the temperature equilibration of an isolated collection of systems which may exchange heat (but not work) energy is positive when the constant-volume heat capacity of each system is a non-negative function of the temperature. (MLH)

The use of science fiction for teaching thermodynamics to introductory students is described. The universality and the tremendous predictive power of thermodynamics is demonstrated.

Discusses that aspect of thermodynamics which is particularly important in chemical process design: the calculation of the equilibrium properties of fluid mixtures, especially as required in phase-separation operations. (MLH)

Describes an experiment in which gas viscosity coefficients over a large temperature range are used to determine the parameters of the intermolecular potential energy and other properties such as virial coefficients. (MLH)

Describes a new method for teaching the Second Law by way of the Carnot cycle. The two features of this method are that the isothermal process is considered first to establish some basic concepts, and then the nonisothermal cyclical process is introduced. (CS)

Presents a classical approximation of the equipartition theorem of thermodynamics. A canonical distribution is assumed and the calculations of Reif are followed to solve for the average potential energy per particle. (CP)

Describes an experiment that utilizes a Joule-Thomson Demonstrator to show the floating nature of the pinch-point in a heat exchanger. (MLH)

Discusses changes in freezing points and boiling points of solutions using simple concepts of thermodynamics to illustrate colligative properties. (MLH)

Describes an undergraduate physical chemistry experiment in phase equilibria which equilibrates potassium iodide solutions of known concentration with solid iodine. (MLH)

Discusses popular erroneous concepts about the thermodynamic standard state of substances, including the fact that standard state is often confused with the concepts of standard temperature and pressure. (MLH)

Describes the use of ethyl or methyl ethanoate mixed with trichloromethane to illustrate intermolecular forces and deviations from Raoult's Law. (MLH)

Chemical stoichiometry is discussed free from kinetic or thermodynamic considerations. The means for determining the following are presented: the number of stoichiometric degrees of freedom, the number of components, a permissible set of chemical equations, and a permissible set of components, for a closed system undergoing chemical reaction.…

Many standard physical chemistry textbooks contain ambiguities which lead to confusion about standard electrode potentials, calculating cell voltages, and writing reactions for galvanic cells. This article shows how standard electrode potentials can be used to calculate cell voltages and deduce cell reactions. (Author/RH)
