which a solute dissolves depends upon the size of the solute particles. Dissolving is a surface phenomenon, since it depends on solvent molecules colliding with the outer surface of the solute. A given quantity of solute dissolves faster when it is ground into small particles than if it is in the form of a large chunk, because more surface area is exposed. The packet of granulated sugar exposes far more surface area to the solvent and dissolves more quickly than the sugar cube.
this is because in cube of sugar the molecules are stucked together but in granuels there are not stuked and have occupied more surface area because they are scattered here and there is why it effects dissolving because in cube of sugar after dissolving outer layer of sugar only we can dissolve sugar inside it so it takes take but in granules there is more surface area exposed i mean that it scatttered or dispersed into many so we can dissolve it faster
