Why sugar dissolves faster in the water when stirred?

Solution
Solubility:
Solubility is the establishment of a new link between solute molecules and solvent molecules.
Solubility is the highest concentration of solute that dissolves in a known concentration of solvent at a particular temperature in terms of quantity.
Sugar dissolves faster in the water when stirred:
When sugar dissolves in water, it dissolves faster if the water is agitated.
The stirring ensures that new solvent molecules are constantly in touch with the solute.
If it is not agitated, the water at the solute's surface becomes saturated with dissolved sugar molecules, making it more difficult to dissolve the new solute.
The sugar cube would dissolve eventually because the random motions of the water molecules would bring enough new solvent into touch with the sugar, but it would take much longer.
It is critical to understand that stirring or breaking up a solute has no effect on the overall amount of solute that dissolves; these operations simply impact the rate of dissolution.
