Question

why particles of potassium permanganate spread easily in water kept at room temp. But not in very cole water

Answer 1

because kinetic energy is more at room temperature

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 .
