Aim: To observe diffusion in a liquid
Method:
1. Half fill your petri dish with cold tap water
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 for 5 minutes.
5. Repeat the experiment using hot water
Observation: We did two ways. With cold water, the crystals expanded slow. When we tried hot water, the crystals expanded fast.
Explanation: When the crystals are in hot water the particles move is in cold water and the particles move slower because the crystal is used to hot environments.
