The process where two different fluids mix together, often through a barrier or membrane.
The interdiffusion of the two gases occurred quickly through the porous material.
Interdiffusion → It is formed from "inter-" (meaning between) and "diffundere" (meaning to pour out). The word describes the process of substances spreading or mixing between each other.
Think of substances 'pouring out' ('diffundere') and mixing 'between' ('inter-') each other — that's what interdiffusion means.
