- Abstract
We investigate Graham's law of effusion in a series of molecular dynamics simulations. We show that the law remains valid not only in a dilute gas, but also in fluids dense enough to cause localization, even when various particles of the system interact according to varying interatomic force laws. Although Maxwellian velocity distribution is a sufficient condition for Graham's law of effusion to hold, it is not strictly necessary, in the sense that the law is obeyed even by systems that deviate significantly from Maxwellian.
