When we put some crystals of potassium permanganate in a beaker containing water, we observe that after sometime, the whole water turns pink. This is due to:

Q. When a crystal of potassium permanganate is placed at the bottom of water in a beaker, the water in the whole beaker turns purple on its own, even without stirring. This is an example of :

Q. When a crystal of potassium permanganate is placed at the bottom of water in a beaker, the water in the whole beaker turns purple on its own, even without stirring. This is an example of :
(a) distribution
(b) intrusion
(c) diffusion
(d) effusion

Q. When a crystal of potassium permanganate is placed in a beaker, its purple colour spreads throughout the water. What does this observation tell us about the nature of potassium permanganate and water?

Assertion:- If we drop a crystal of potassium permanganate into a beaker containing hot water and another beaker containing cold water then the rate of mixing of the potassium permanganate in the hot container is more as compared to the cold container.

Reason:- Movement of particles increases with the increase in temperature.
