Determining the Pressure inside an Unopened Carbonated Beverage Hans de Grys
Determining the pressure of carbon dioxide inside a sealed soft drink can represents a challenging student exercise. Several methods are discussed for solving the problem, including applying the ideal gas law, gas collection via water displacement, and Henry's law.

What Are Students Thinking When They Pick Their Answer? Michael J. Sanger and Amy J. Phelps
330 students were asked to answer a multiple-choice question concerning gas properties at the microscopic level and explain their reasoning. Of those who selected the correct answer, 80% provided explanations consistent with the scientifically accepted answer, while 90% of the students who picked an incorrect choice provided explanations with at least one misconception.

Steel Wool and Oxygen: A Look at Kinetics James Gordon and Katherine Chancey
An experimental method is described to study the kinetics of the reaction of the iron in steel wool with molecular oxygen. A calculator-based data collection system is used with an oxygen gas sensor to determine the order of the reaction with respect to oxygen. Using the graphical method, students determine that the reaction follows first-order kinetics with respect to oxygen.

Applying Chemical Potential and Partial Pressure Concepts To Understand the Spontaneous Mixing of Helium and Air in a Helium-Inflated Balloon Jee-Yon Lee, Hee-Soo Yoo, Jong Sook Park, Kwang-Jin Hwang, and Jin Seog Kim
In developing this laboratory, our initial motivation for the analysis of gases in a balloon was to answer simple and basic questions, such as, Why does a helium-charged balloon left in the air always drop in a few days? Is leakage of helium the only cause of the drop? What is the composition of the gas in the balloon when it falls after deflation? Students were intrigued by these questions, too, as they analyzed the variation over time in the composition in a balloon inflated with helium. Using the concepts of partial pressure and chemical potential, the laboratory experiment described effectively investigates the diffusion process and the behavior of gas molecules for teaching these concepts in general and physical chemistry.

The Determination of the Percent of Oxygen in Air Using a Gas Pressure Sensor James Gordon and Katherine Chancey
A new detection method is applied to a classic experiment in which gaseous atmospheric oxygen in a test tube is reacted with the iron in steel wool to produce rust. A gas pressure sensor interfaced to a calculator-based data collection system was used to measure the percent of oxygen in the air as the reaction proceeded. The results from the calculator-based experiment were compared to the results from a more traditional water-measurement experiment. The average percent of oxygen obtained using the calculator system was 19.4 0.4%.

On the Buoyancy of a Helium-Filled Balloon John E. Harriman
It is shown by expansion of the exponential in the barometric formula that the forces due to pressure acting on a balloon are of the form (PV/RT)Mg and that results agree with those suggested by Archimedes principle. Einstein's equivalence principal provides an answer to what balloons will do in an accelerated car.

Henry's Law and Noisy Knuckles Doris R. Kimbrough
Presented here is the application of Henry's law to the noise associated with "cracking" knuckles. Gases dissolved in the synovial fluid in joints rapidly come out of solution as the joint is stretched and pressure is decreased. This "cavitation" produces a characteristic noise.

A Precise Method for Determining the CO2 Content of Carbonate Materials Donald L. Pile, Alana S. Benjamin, Klaus S. Lackner, Christopher H. Wendt, and Darryl P. Butt
The design and use of a buret apparatus for CO2 gas capture and mass determination are described. The derivation of a comprehensive equation to determine the CO2 mass and percent carbonation of the material is outlined. Experimental factors such as temperature and pressure, including elevation effects, and apparatus parameters are discussed and incorporated into one general equation.

Revealing the secret of the Arctic bomb Pearson, Earl F.
Arctic bombs and hurricanes can appear to be contradictory to gas law concepts commonly taught to chemistry students. While these phenomena can be explained as applications of simple gas laws, the explanations can be more effective if an apparent contradiction is drawn between students' understanding and the observed pressure-temperature relationship in these two examples.
