Cp/Cv Ratios Measured by the Sound Velocity Method Using Calculator-Based Laboratory Technology Mario Branca and Isabella Soletta The values ? = Cp /Cv (heat capacity at a constant pressure / heat capacity at constant volume) for air, oxygen, nitrogen, argon, and carbon dioxide were determined by measuring the velocity of sound through these gases at room temperature using Calculator-Based Laboratory Technology. Branca, Mario; Soletta, Isabella. J. Chem. Educ. 2007, 84, 462.

A Visual Aid in Enthalpy Calculations Sebastian G. Canagaratna This article discusses the use of enthalpy-temperature diagrams for reactants and products as a visual aid in the teaching of reaction-enthalpy calculations. By the use of such diagrams the division of the process into a part involving a chemical reaction without a temperature change and a part involving only a temperature change is made visually concrete. Canagaratna, Sebastian G. J. Chem. Educ. 2000, 77, 1178.

The Ammonia Smoke Fountain: An Interesting Thermodynamic Adventure M. Dale Alexander The ammonia smoke fountain demonstration utilizes a modification of the apparatus used in the standard ammonia fountain. The modification allows for the introduction of hydrogen chloride gas into a flask of ammonia rather than water. The flow rate of hydrogen chloride gas into the flask in the smoke fountain is not constant, but periodic; that is, the smoke puffs from the end of the tube. This unexpected behavior elicits an interesting thermodynamic explanation. Alexander, M. Dale. J. Chem. Educ. 1999, 76, 210.

A Brief History of Thermodynamics Notation Rubin Battino, Laurence E. Strong, Scott E. Wood This paper gives a brief history of thermodynamic notation for the energy, E, enthalpy, H, entropy, S, Gibbs energy, G, Helmholtz energy, A, work, W, heat, Q, pressure, P, volume, V, and temperature, T. In particular, the paper answers the question, "Where did the symbol S for entropy come from?" Battino, Rubin; Strong Laurence E.; Wood, Scott E. J. Chem. Educ. 1997, 74, 304.

A gas kinetic explanation of simple thermodynamic processes Waite, Boyd A. Proposes a simplified, semi-quantitative description of heat, work, and internal energy from the viewpoint of gas kinetic theory; both heat and work should not be considered as forms of energy but rather as different mechanisms by which internal energy is transferred from system to surroundings. Waite, Boyd A. J. Chem. Educ. 1985, 62, 224.
