You will compare the efficts of particle size by comparing three dyes of different molecular weights: potassium permanganate, which has the methylene blue lowest molecular weight; methylene blue, which has a middle molecular weight; and Congo red, which has the molecular weight. To compare the effect of concentration, you will be using two different concentrations of 1 Obeain four empty Petri dishes. Label the plates 1, 2, 3, and 4.

Explanation / Answer

Diffusion refers to the net movement of atoms or molecules from a region of their higher concentration to the region of their lower concentration.

It depends upon a number of factors:

As we can see, temperature is one of the most crucial factors which regulates the rate of diffusion.

Thus, in this experiment, the dye in the hot beaker will travel a lot faster than that in cold beaker. For e.g.

Time. Hot . Cold
