Water, Aqueous Solutions ChemMatters, Feb. 2002, p. 2, Hydrogen Beer Elements Gases, solubility, Henry s Law The entire article is a great story. Terrific story about hydrogen beer, a beer said to contain hydrogen gas rather than carbon dioxide. Hydrogen beer is a hoax, an urban legend but was actually able to fool enough educated people so that it made it to a reputable physics Website as well as a chemistry textbook. Applying simple notions of solubility, etc., should have revealed its obvious nonvalidity.

Kinetic Theory Example of a practical application of heat flow in nature Energy, kinetic theory, heat Animals, adaptations Interesting story of how a duck uses a clever arrangement of veins and arteries to prevent excessive heat loss through its feet when swimming in icy water Given the large surface area of a duck s feet, it would seem that they would lose an excessive, perhaps unrecoverable amount of heat when swimming in icy water. But through an ingenious arrangement of veins and arteries, they manage to keep heat loss to a minimum. ChemMatters, Dec. 2000, pp , Noisy Knuckles and Henry s Law Gas laws, aqueous solutions Henry s Law Structure of a knuckle joint Article describes the structure of the human knuckle and what happens when you crack a knuckle.

Water, Aqueous Solutions ChemMatters, Feb. 1996, pp , The Lake Nyos Disaster Gases Water, aqueous solutions On August 21, 1986, a cloud of carbon dioxide was released from Lake Nyos in Cameroon, West Africa, killing 1,724 people and several thousand animals. Article explains how carbon dioxide accumulated in Lake Nyos over a period of years, why it remained in the lake at high concentrations, and what probably caused it to be rapidly released, resulting in the disaster. ChemMatters, Oct. 1984, pp , Popcorn and Activity Personal experience with popcorn Scientific principles that underlie its popping behavior Gas laws The structure of popcorn This article discusses the structure of popcorn and what results in its popping when heated. The article is followed by a student activity that investigates and even measures the percent moisture in a popcorn kernel.
