What is the difference between diffusion and dissolving?
Asked by: Agy Jojy
Answer
Diffusion is the passage of particles from an area of higher concentration to an area of lower concentration.
Dissolving is the bombardment of a solvent (e.g. water) on solute molecules (something that can
dissolve, like sugar) forcing them apart. The solute mixes with a solvent to form a solution.
