Question

What are the factors influencing diffusion, whether the arrangement of atoms in the substance that diffuse or the arrangement of atoms of the medium in which the substance is kept.

Answer 1

(1) Diffusion depends on both material that is diffusing and the material it is diffusing through. 

(2) At certain temperature, all particles have the same average energy. 

(3) This means that lighter atoms, such as hydrogen, carbon, oxygen and nitrogen travel faster and are more mobile than larger atoms such as copper or iron. 

(4) Materials made of these lighter atoms diffuse faster than heavier materials.
