JavaScript Programs To Calculate Thermodynamic Properties Using Cubic Equations of State  
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. These two educational JavaScript programs perform calculations using cubic equations of state and, equally importantly, explain how the calculations are performed.

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.

Simple Dynamic Models for Hydrogen Bonding Using Velcro-Polarized Molecular Models  Emeric Schultz
This article describes the use of models that dynamically illustrate the unique characteristics of weak intermolecular interactions, specifically hydrogen bonds. The models clearly demonstrate that H-bonds can break and reform while covalent bonds stay intact. The manner in which the models form and break H-bonds reflects the geometric and statistical manner in which H-bonding actually occurs and is not contrived. The use of these models addresses a significant area of student misconceptions. The construction of these molecular models is described.

Are Fizzing Drinks Boiling? A Chemical Insight from Chemical Education Research  Alan Goodwin
The suggestion that fizzing drinks are examples of liquids boiling at room temperature has proved to be controversial among both chemists and chemical educators. This paper presents a case for believing this everyday system to be a good example of a boiling solution and the consequent separation of carbon dioxide from the solution to exemplify fractional distillation.

Thermodynamics of Water Superheated in the Microwave Oven  B. H. Erné
Water is conveniently heated above its normal boiling point in a microwave oven in a glass microwave oven teapot. Water stops boiling soon after heating is interrupted, but subsequently added rough particles can still act as nucleation centers for a brief, spectacular burst of steam bubbles. The heat to make those steam bubbles obviously comes from the water itself, so that one can conclude that the boiling water was superheated, which is confirmed with a thermometer.

A Closer Look at Phase Diagrams for the General Chemistry Course  Stephen A. Gramsch
The information provided by the high-pressure phase diagrams of some simple systems (carbon dioxide, water, hydrogen, and iron) can provide a useful extension to the traditional discussion of phase diagrams in the general chemistry course. At the same time, it can prepare students for a more illuminating presentation of the concept of equilibrium than is possible through the discussion of gas phase, acid-base, and solubility product equilibria alone.
