Stirring a solute into a solvent speeds up the rate of dissolving because it helps distribute the solute particles throughout the solvent. For example, when you add sugar to iced tea and then stir the tea, the sugar will dissolve faster.
Explanation: solid solute are difficult to dissolve in a solvent because if they are closely packed and this makes it difficult for liquids to penetrate through the but when the surface tension is increased by grinding the solid solute into powered form this makes it dissolve faster
Taking a cube sugar as an example it will involve lots of stirring to make it dissolve while the granulated powered sugar dissolve easily and readily
