Diffusion Experiment
Today in chemistry we have been learning about particles and diffusion.
Diffusion is when particles moving from high to low concentrations spread and become less concentratedDiffusion occurs in liquids and gases
The experiment we are doing is seeing how diffusion works in hot and cold water.
My hypothesis is that the particles will diffuse faster in hot water because the particles are already moving very fast which will cause them to spread apart faster.
Method:
1. Half fill your petri dish with cold tap water
2. Place the petri dish on your work bench and allow the water to become settled.
3. Using the tweezers, place a single drop of potassium permanganate in the centre of the petri dish.
4. Observe for 5 minutes
5. Repeat the experiment using hot water.
Equipment: Petri dish, water, tweezers and potassium permanganate power.
Results
It turned out as I expected and the hot water diffused much faster than the cold water.
The cold water ended up diffusing in a circle.
