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.

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.
