describe an activity to prove that water is matter
Answers
Answer:
when we pour water in a container. it tooks the shape of the exact container we poured it into. thus it says that, water is a matter.
Explanation:
(i) Take 2-3 crystals of potassium permanganate and dissolve them in 100 ml of water.
(ii) Take out approximately 10 ml of this solution and put it into 90 ml of clear water.
(iii) Take out 10 ml of this solution and put it into another 90 ml of clear water.
(iv) Keep on diluting the solution like this 5 to 8 times.
(v) This experiment shows that just a few crystals of potassium permanganate can change colour of a large volume of water (about 1000 L).

Fig: Set up to explain that particles of matter are very small. With every dilution, though the colour becomes light, it is still visible.
So, we conclude that there must be millions of tiny particles in just one crystal of potassium
permanganate, which kept on dividing themselves into smaller and smaller particles.
