The Problem bother on the diffusion of substance
What is diffusion?
This can be defined as the movement of particles from a region of higher concentration to a region of lower concentration till equilibrium is reached
Explanation:
From the experiment seeks to measure the diffusion distance against time
Now when dye is dropped in water, the particles/molecules of the dye interacts with the molecules of water hence there is a mixtures which cause the dye to move from the initial position of higher concentration to lower concentration.
Hence the movement from the 0 mm mark increases in both directions
