Mean free path

The rate of the transfer process in gases, in particular diffusion, depends on the free path of the molecules. The video discusses a simple way to estimate this value.
Keywords: thermal motion of molecules, molecular kinetic theory, scattering cross section, diffusion.

Great explanation! The cup is 10 cm tall (0.1 meters) and the molecule's mean free path is 0.1 microns (0.1 × 10^-6 meters).
Number of Collisions: Molecule makes ~1,000,000 collisions on average before escaping.
Distance Covered: It covers approx. 0.1 meters (10 cm) in total distance.
Thanks for the clear breakdown! hope those were hiccups, stay healthy.
