Epstein, Mark G.; Laszlo, Matthew W.; Mayer, Steven G. – Journal of Chemical Education, 2010
We present an adaptation to an experiment previously published in this "Journal". The experiment was designed to determine the heat capacity ratios of gases by measuring the speed of sound using a modified Kundt's tube. The experiment yielded excellent results for all of the gases and gas mixtures measured. Although elegant in its simplicity, it…
