Determination of Boltzmann constant by gas expansion method

In this paper, we present a new method to determine the numerical value of the Boltzmann constant k and its uncertainty. We have used Nitrogen gas in different pressure values in the range 56 kPa - 100 kPa, for three different volumes.In this experiment, we have used a simple idea called static expansion method, simple equipment, and simple equation for calculations in order to determine the Boltzmann constant.
