The Behavior of Matter - Diffusion
Aim: To observe diffusion in a liquid.
Equipment: Petri dish, Water, Tweezers, A crystal of potassium permanganate.
Method:
1. Half fill your petri dish on your workbench and allow the water to become settled.
2.Place the Petri dish on your workbench and allow the water to become settled.
3. Using the tweezers, place a single crystal of potassium permanganate in the center of the petri dish.
4. Observe 4 minutes
5. Repeat the experiment using hot water.
Results:
We had 4 minutes to see if the potassium spread faster and wider in cold water or hot water it turned out that the cold water caused to to go slower.
Discussion:
When a particle is cooled it will go slower rather that if it was heated up this is why the warm water potassium spread faster than the cold water one.
