Question

give reason particle of potassium permanganate spread easily in water kept at room temperature but not in very cold water.

Answer 1

Because in hot water the rate of diffusion increases. So the particles of KMnO4 spread in hot water easily.

Answer 2

Answer:

Particles of potassium permanganate dissolve easily at room temperature but not in cold water this is all because at room temperature the Kinetic energy of the water molecules are higher as compared to the water molecules in cold water because lowering in temperature causes a decrease in velocity of collision of water .
