Method
1.Half fill your petri dish on your work bench with cold tap water.
2.Place your petri dish on your work bench and allow the water to become settled.
3.Using the tweezers, place a single crystal of potassium permanganate in the centre of the petri dish
4.Observe for 5 minutes.
5.Repeat the experiment using water.
Results:
Hot water
Observation:
We first put the solute in the cold solvent then we observe.We saw that it was very slow and it took more then 5 minutes to spread.Then we tried it with hot water and we saw that it spread a lot quicker.So why did hot water spread the potassium permaganate quicker? Because it was hot and the particles were spreading more quickly.
