Final answer:
To increase the dissolving rate of sugar in water, one should stir the solution, maximize the sugar's surface area by using granulated sugar, and increase the water's temperature.
Step-by-step explanation:
The most effective means of increasing the dissolving rate of sugar in water involves a combination of factors. Stirring, or agitation of the solution, is crucial because it facilitates more frequent contact between water molecules and sugar, enhances collision frequency, and prevents local saturation around the sugar. Another significant factor is the surface area of the sugar; granulated sugar has more surface area exposed to the water than a sugar cube, resulting in a faster dissolution. Finally, temperature plays a key role; sugar dissolves faster in hot water as the increased temperature grants water molecules more energy, leading to more effective collisions with the sugar particles.
It is important to note that while these methods can increase the rate at which sugar dissolves, they do not change the total amount of sugar that can be dissolved in the water, which is determined by its solubility. Once the solution has reached its solubility limit, additional sugar will not dissolve regardless of stirring or temperature.
