"Concept Learning versus Problem Solving": Does Particle Motion Have an Effect? Michael J. Sanger, Eddie Campbell, Jeremy Felker, and Charles Spencer
210 students were asked to answer a static, particulate-level, multiple-choice question concerning gas properties. Then they viewed an animated version of the question and answered the multiple-choice question again. The distribution of responses changed significantly after students viewed the animation.

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.

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.

Are Fizzing Drinks Boiling? A Chemical Insight from Chemical Education Research Alan Goodwin
The suggestion that fizzing drinks are examples of liquids boiling at room temperature has proved to be controversial among both chemists and chemical educators. This paper presents a case for believing this everyday system to be a good example of a boiling solution and the consequent separation of carbon dioxide from the solution to exemplify fractional distillation.

Using a Computer Animation to Improve Students' Conceptual Understanding of a Can-Crushing Demonstration Michael J. Sanger, Amy J. Phelps, and Jason Fienhold
This paper reports some of the misconceptions that were identified from these students' explanations. As a result of these misconceptions, a computer animation depicting the chemical processes occurring in the can-crushing demonstration was created.

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.

Does a one-molecule gas obey Boyle's law? Rhodes, Gail
Because the kinetic molecular theory provides a plausible explanation for the lawful behavior of gases, it should be treated in enough depth to show students that the theory accounts for all of the important aspects of ideal gas behavior.

A gas kinetic explanation of simple thermodynamic processes Waite, Boyd A.
