The rate of diffusion (J) depends on several physical factors. Briefly desribe an experiment that demonstrates J varies inversely with the size of the diffusing particle. Please be specific. For animal physiology class. (Derived from Fick\'s equation) Solution Experiment To show Diffusion: When one will pour dark color liquid such as ink in a bucket of clean water whole color of bucket will be blue because of diffusion of dark color molecules from higher concentration to area of lower concentration There are several factors which affect rate of diffusion such as.
