Breaking up, crushing or grinding a sugar cube before adding it to water increases the sugar's surface area. The more surface area a solute has, the faster it will dissolve because more particles of the sugar can interact with the water. This means the finer the sugar particles, the faster it will dissolve.

How does crushing affect the rate of dissolving?

Crushing it has increased the surface area so it speeds up the dissolving process but doesn't change maximum solubility. Crushing it has really no affect on solubility because we have not stirred it at all. Crushing it has increased the surface area so it increases the maximum solubility.

Does crushing make a solute dissolve faster?

Crushing it has really no affect on solubility because we have not heated it at all. Crushing it has increased the surface area so it speeds up the dissolving process but doesn't change maximum solubility. Crushing it has increased the surface area so it increases the maximum solubility.
