To prove that rate of diffusion decreases with the addition of density this activity can be conducted.
Take two beakers with water in them.
- Take two beakers filled with water.
- Put a drop of blue ink slowly along the sides of the first beaker and honey in the same way in another beaker.
- Leave it undisturbed.
- We observe that honey diffuses slowly as compared to ink.
This experiment shows that lesser the density, faster the rate of diffusion.
