    The overall purpose of the experiment is to observe the change of pressure as three different gases; N2‚ He‚ and an unknown gas effuses through a pinhole into a vacuum environment. Each gas has a different pattern of changing the pressure depending on its molecular mass‚ which is related to the kinetic theory of gases‚ where heavier gases (N2) effuse slower than lighter gases (He). The experiment setup was prepared‚ measurement of change of pressure as a function of time were recorded. After performing
