Diffusion lab

Today in lab we experimented with diffusion which is the movement of molecules from high to low concentration to create balance.

-The energy that allows random motion of molecules to occur is called heat.

We first added potassium permanganate to room temperature water, the water bath, and ice water.
-The water bath dissolved fastest because it was hot, and the ice dissolved slowest due to the cold temperature.

Second we placed two holes with a cork bore in the agar. We then added the dye methylene blue and potassium permanganate to each hole and waited for 20 minutes.
-The potassium permanganate moved at a faster rate of diffusion, because its a smaller molecule than the methylene blue.
