What is Diffusion...
Diffusion is when particles are moving from high concentration to low concentration in liquid and gas.
Aim: to see if hot or cold water diffuse particles faster or slower than each other.
I think the hotness will make it diffuse faster.
Method:Place the peril dish on your workbench and allow the water inside it to settle.
Using the tweezers place the single bit of potassium in the centre of the dish.
Observe for 5 minutes.
Repeat the experiment with hot water.
Results:Hot water diffused faster than the cold water
