A large crystal of potassium manganate was placed in the bottom of a beaker of cold water and left for several hours describe what

After 5 minutes the crystals colour covers the bottom. and eventually the water turns purple.If you will take hot water it will diffuse faster.

Explanation:

Molecular diffusion, often simply called diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero. The rate of this movement is a function of temperature.So  the water is cold so the diffusion will occur slowly.Diffusion occurs when particles move from an area of high concentration to an area of low concentration. The factors affecting rate of diffusion are: concentration, temperature, mass of the particle and properties of the solvent in which diffusion occurs. Faster movement equals faster diffusion.

I hope this answer help you.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .

I'm not sure but i will try to find out
