How does stirring at room temperature achieve the same effect as boiling liquid?

Question

Salt and sugar dissolve in water at very high temperatures, roughly 100° C. Stirring achieves the same effect at room temperature or lower. How is this possible?

In: Physics

Answer 1

Salt and sugar dissolve at low temperatures as well. Adding heat to the solution increases the solubility, which means the water can dissolve MORE salt/sugar than room temperature water. As for the stirring, it speeds up the dissolution of the salt/sugar. But dissolution occurs at high AND low temperatures. The factors you mentioned are just ways to either dissolve more, or speed up the dissolution.
