A Simple Laboratory Experiment for the Determination of Absolute Zero  Myung-Hoon Kim, Michelle Song Kim, and Suw-Young Ly
A novel method that employs a remarkably simple and inexpensive apparatus and is based on the extrapolation of the volume of a given amount of dry air to zero volume after a volume of air trapped inside a 10-mL graduated cylinder is measured at various temperatures.

Graham's Law and Perpetuation of Error  Stephen J. Hawkes
Grahams Laws of effusion and diffusion are used in recent articles for traditional experiments to which they do not in fact apply and for which they give the wrong answer.

Measurement scales: Changing Celsius to Kelvin is not just a unit conversion   Nordstrom, Brian H.
The key to understanding the difference between Celsius and Kelvin lies in the different types of measurement scales. Students may have an easier time manipulating equations (such as gas laws) if they knew the difference between these scales.

An alternative to using the PV = nRT equation   Desmarais, George
This author shares his application of the factor-label method to solving gas problems which involves using the ideal gas constant as the starting point in the relationship.

Reflections upon mathematics in the introductory chemistry course  Goodstein, Madeline P.
It is the purpose of this paper to call attention to the lack of mathematical competence by chemistry students and to invite consideration of one conceptual scheme which may be used to unify the mathematical approach.

Pressure calculations   Schultz, Charles W.
This question requires students to be able to distinguish two kinds of pressure: Boyles law pressure of gas (that depends on volume) from the equilibrium vapor pressure above a liquid (that does not).

Teaching the method of successive approximations  Nassiff, Peter J.; Boyko, E. R.
The purpose of this papers is to help the teacher show the student why basic methods of successive approximations work, how they may be applied, and under what conditions it will be successful.
