Zero gravity allows one the opportunity to study predictions on the molecular behavior of an ideal gas using macroscopic test objects. We will use this fact to study two types of diffusion: diffusion into a space and diffusion due to a density gradient. Tests of diffusion into space will be performed to demonstrate the dependence of the flux on angle. Tests will be made on both low and high number densities of 1/4 inch, 3/8 inch, 5/8 inch spheres. Tests of diffusion due to a density gradient will be performed to calculate the coefficient of self diffusion and the mean free path length of a diffusive gas. Tests will be made on spheres with a 50/50 ratio and on spheres with a one to many ratio.
