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.
