What particle diffused the farthest, potassium permanganate or methylene blue? what was the factor in the difference in diffusion rates?

Diffusion is a physical process where particles move from higher concentration to lower concentration. The particles which diffuses could be liquid, gas and solid.

Methylene blue has a high molecular weight compare to potassium permaganate , so the lighter molecules diffuses more rapidly than heavier molecules.

Temperature, density of the diffusing particles , medium of diffusion and concentration gradient these factors affect the diffusion rate.

it would lead to upper respiratory infections and pneumonia.

not sure if this what   you'r looking for would be percent composition
