  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.
