Question

When completing the diffusion of a dye through water, where does the 0 mm mark on your ruler go?

Answer 1

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
