Fog Machines, Vapors, and Phase Diagrams  Ed Vitz
This series of demonstrations elucidate the operation of commercial fog machines using common laboratory materials and can be adapted for elementary through tertiary levels. The formation of fogs is discussed in terms of the phase diagram for water and other chemical principles.

Chemistry of Moth Repellents  Gabriel Pinto
A real-life example consisting of the study of the different substances used as moth repellents is presented to introduce students to miscellaneous topics such as sublimation, intermolecular forces, insecticides, and the effect of moths on clothes. A set of questions about the most common moth repellents, well known to students, is used to motivate them to understand several everday phenomena through chemistry concepts.

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.

Teaching Distillation Knowledge: A Video Film about Distillation Bridging a Gap Between Theory and Practice  Martin J. Goedhart, Hanno van Keulen, Theo M. Mulder, Adri H. Verdonk, and Wobbe De Vos
The authors observed that first year students hardly used their knowledge of phase theory in the design and performance of distillations. They therefore developed a video in which they confront students with the boiling properties of liquid mixtures.

Experiments of Modern Chemistry: Simultaneous Recording of Multiple Cooling Curves  Ronald A. Bailey, Sudhen B. Desai, Norbert F. Hepfinger, Henry B. Hollinger, Peter S. Locke, Kenneth J. Miller, James J. Deacutis, Donald R. VanSteele
An apparatus for simultaneous recording of six heating/cooling curves of metallic mixtures is described. Data are recorded using computer data acquisition and temperature-time data displayed and printed out for evaluation.

Kinetics in Thermodynamic Clothing: Fun with Cooling Curves: A First-Year Undergraduate Chemistry Experiment  Casadonte, Dominick J., Jr.
A series of experiments examining the phenomenon of cooling by producing part of the cooling curve for water at different initial temperatures, focussing on the fact that the curve is nonlinear (unlike the information presented in many texts).

Critical point phase separation in binary liquid mixtures   Bowen, L. H.; Benevides, M. L.
Critical point demonstrations are not usually practical to perform. This author provides a suggestions using hexane, nitrobenzene, triethylamine, water and phenolphthalein.
