Diffusion Experiment

This week we have been learning about diffusion. Diffusion is where particles go from a high concentration to low concentration.

Aim: Investigate if particles diffuse faster in hot or cold water.

Hypothesise: I think it will diffuse faster in hotter water because it is hotter.

Equipment: We used hot water, cold water, potassium manganate, A beaker, and a petri dish.

Method: Fill one petri dish with hot water and one with cold. Next put a tiny bit of potassium mangante in both dishes preferably at the same time. Then you wait.

Results: They were at the same pase as they were spreading and I think it doesn't matter what type of water it is in it will spread at the same pase. But someone came along and shook our experiment and it ruined it. But by looking at the other experiments I think they spread at the same time. As you can see the dark spot is at the same pace as the non shooken one. Here are some images:

  1. Hi Cody! What a shame about your experiment. Your hypothesis was actually correct! Particles should diffuse faster in hot water as the hot water will give the particles more energy so they spread around quicker :)
