What is the difference between diffusion and dissolve?
Diffusion is the spread of particles from an area of higher concentration to an area of lower concentration. Diffusion can occur in gas or liquid.Dissolving occurs when one substance, the solvent, supports the particles of another substance, the solute, to form a solution. The two processes are similar.Example:Sugar in the bottom of a cup of coffee will slowly diffuse into the bottom of the cup dissolving as it goes. When we stir the coffee we make the process faster and the dissolving is uniform without a higher concentration at the bottom of the cup.Perfume or petrol (gasoline) in a container in the corner of the room will slowly diffuse out and we can smell it even when we are not next to the container. Again the concentration is higher the closer we are to the container.
