Diffusion Experiment

Chemistry

Aim: To see if hot or cold diffuse faster 

Equipment: Petri dish, water,tweezers,a crystal of potassmium permanganate.

Method: 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 snigle crystal of potassium permanganate in the centre of the petri dish.

4. observe for five minutes.

5. repeat the experiment using hot water.

Results: the particales are moving from high to low concentration in the petri dish

In hot water:Diffused Faster

In cold water: Diffused Slower

Discussion: Hot diffused faster than the cold water because the tempatrue in the hot water is high and the cold is low and the particals breaks apart but slow.
