Hello! Welcome back to another Wednesday Science period! Today we did a little experiment resonating with diffusion, here's what I used!
Equipment:
Tweezers
Petri Dish
KMn04 (Potassium)
Cold & Hot water
Question: Does temperature speed up or slow down Diffusion?
Result/Observation: Crystal in the hot water grew and expanded 2x the size of the crystal in the cold water. Why? The particles in the hot water are moving faster than the particles in the cold water, which means that diffusion will happen quicker.
Conclusion: The experiment was interesting because that was the first time I had seen something like that. It was also cool to see the effect the different temperatures of water would have on the potassium permanganate.
