d entropy of d wrld tends 2 a maximum  John W. Moore
It is natural to wonder what happens to the writing skills of those who send text messages. It has been suggested that modern technology and multitasking significantly reduce our ability to concentrate and perhaps alter the way we think and process information. If this is correct, the implications for education are profound.

Factors That Influence Relative Acid Strength in Water: A Simple Model  Michael J. Moran
The pKa's of diverse aqueous acids HA correlate well with the sum of two gas-phase properties: the HA bond-dissociation enthalpy and the electron affinity of the A radical. It is suggested that rather than bond strength alone or bond polarity, the sum of the enthalpies of these two steps is a fairly good indicator of relative acidity.

Rotational Mobility in a Crystal Studied by Dielectric Relaxation Spectroscopy. An Experiment for the Physical Chemistry Laboratory  Madalena S. C. Dionísio, Hermínio P. Diogo, J. P. S. Farinha, and Joaquim J. Moura-Ramos
In this article we present a laboratory experiment for an undergraduate physical chemistry course. The purpose of this experiment is the study of molecular mobility in a crystal using the technique of dielectric relaxation spectroscopy. The experiment illustrates important physical chemistry concepts. The background of the experimental technique deals with the concepts of orientational and induced polarization and frequency-dependent relative permittivity (or dielectric constant). The kinetic concepts of temperature-dependent relaxation time, activation energy, and activation entropy are involved in the concept of molecular mobility.

Cubic equations of state are widely used by chemists and chemical engineers to predict the thermodynamic properties of both pure substances and mixtures. In particular, these equations enable predictions concerning the temperature and pressure at which vaporliquid equilibrium occurs.

The q/T Paradox: Which "Contains More Heat", a Cup of Coffee at 95°C or a Liter of Icewater?  Ed Vitz and Michael J. Schuman
In this demonstration, heat is removed from 10 cm3 of water at ~95C and 42 cm3 of water at ~0C by adding each to a measured sample of liquid nitrogen. The heat removed from the water boils the N2(l), and the quantity of liquid nitrogen that is evaporated by boiling is determined. The quantity of heat that was absorbed is calculated from the heat of vaporization of liquid nitrogen and found to be about 10,000 J in the case of the hot water and 25,000 J in the case of the icewater.

A Pedagogical Simulation of Maxwell's Demon Paradox  D. López and C. Criado
Teaching thermodynamics from the microscopic point of view can help students develop an intuitive understanding of its concepts. This program simulates, at the microscopic level, two gas chambers with an opening between them. The program allows students or their instructors to set up simulations that illustrate the thermodynamics and statistical behavior of the system. The user determines the basis for whether the demon permits or denies passage of particles through the opening using information from the microscopic level, such as specific particle velocity. Students can track and analyze how this affects particle distribution, thermal equilibrium, relaxation time, diffusion, and distribution of particle velocities.

Conceiving of Concept Maps To Foster Meaningful Learning: An Interview with Joseph D. Novak  Liberato Cardellini
Joseph Novak, the inventor of concept maps, explains in this interview how that idea was born thirty years ago. As a student he developed a passion for education, trying to find better ways to educate people and help them "learn how to learn". Concept maps can profitably be used to represent knowledge in every field of study: they help students to construct new learning and are also useful for teachers to discover possible misconceptions in the students' own construction. Novak discusses the advantages of meaningful learning and the foundations of his theory of education based on "human constructivism" and he summarizes it in a concept map.

Many general chemistry textbooks have errors or omissions in their rules for predicting solubility that the author highlights and attempts to correct. In addition, it is proposed that the following changes be made to the discussion of solubility so that students and teachers can have a greater understanding of solubility.

A Web-Based Interactive Homework Quiz and Tutorial Package To Motivate Undergraduate Chemistry Students and Improve Learning  Ben Freasier, Grant Collins, and Paula Newitt
This study presents a Web-based interactive homework quiz and tutorial package that we have devised to improve the learning of first-year undergraduate chemistry students. We developed this automated scheme, based on WWWAssign, to produce randomly generated quizzes from a large database of questions, instantaneously grade that homework, give a fully-worked solution, and provide individually targeted tutorial assistance.

Playing-Card Equilibrium  Robert M. Hanson
A simple hands-on simulation suitable for either classroom use or laboratory investigation involves using a standard deck of playing cards to explore the statistical aspects of equilibrium. Concepts that can be easily demonstrated include fluctuation around a most probable distribution, Le Chtelier's principle, the equilibrium constant, prediction of the equilibrium constant based on probability, and the effect of sample size on equilibrium fluctuations.

Vapor Pressure Lowering by Nonvolatile Solutes  Gavin D. Peckham
This short article highlights a fundamental error that is entrenched in introductory chemistry textbooks. It is true that the addition of a nonvolatile solute causes a lowering in the vapor pressure of a solution. The error lies in attributing this vapor pressure lowering to the "blocking" of surface sites by nonvolatile particles. This is a totally fallacious argument for a number of reasons and the true explanation is to be found in the entropy changes that occur as a nonvolatile solute is added to a solution.
