A Precise, Simple, and Low-Cost Experiment to Determine the Isobaric Expansion Coefficient for Physical Chemistry Students
Pe´rez, Eduardo
Journal of Chemical Education, v92 n7 p1250-1253 Jul 2015
The procedure of a physical chemistry experiment for university students must be designed in a way that the accuracy and precision of the measurements is properly maintained. However, in many cases, that requires costly and sophisticated equipment not readily available in developing countries. A simple, low-cost experiment to determine isobaric expansion coefficient has been designed and successfully implemented. The practice includes measurement of density at controlled temperatures and mathematical and graphical treatment of data. In spite of the simplicity of the experiment, the precision and accuracy of the measurements are not forfeited.
