Abstract

This paper presents measurement of Boltzmann's constant by observing Brownian motion of polystyrene beads suspended in water. The measured value of the Boltzmann's constant is k = (1.49 ± 0.14) x 10^-23 J/K which has percent error of 7.65% as compared to the accepted value (k =1.38 x 10^-23 J/K). We also present method of doing video microscopy designed for an undergraduate laboratory.
