Fog Machines, Vapors, and Phase DiagramsEd 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. Vitz, Ed. J. Chem. Educ.2008, 85, 1385.

Understanding the Clausius–Clapeyron Equation by Employing an Easily Adaptable Pressure CookerMonica Galleano, Alberto Boveris, and Susana Puntarulo Describes a laboratory exercise to understand the effect of pressure on phase equilibrium as described by the ClausiusClapeyron equation. The equipment required is a pressure cooker adapted with a pressure gauge and a thermometer in the lid, allowing the measurement of the pressure and the temperature of the chamber containing the water heated until vaporization. Galleano, Monica; Boveris, Alberto; Puntarulo, Susana. J. Chem. Educ.2008, 85, 276.

Water #1 (GCMP)David M. Whisnant Water #1: this is a resource in the collection "General Chemistry Multimedia Problems". Isotopes are forms of the same element composed of atoms that have different numbers of neutrons. In this problem we will begin by observing the properties of water containing two isotopes of hydrogen. General Chemistry Multimedia Problems ask students questions about experiments they see presented using videos and images. The questions asked apply concepts from different parts of an introductory course, encouraging students to decompartmentalize the material.
