Dissolving is a familiar process. Salt, for example, dissolves readily in water, as does sugar in coffee. On a molecular level, dissolving consists of the molecules of a solute -- salt or sugar -- encountering and pairing up with the molecules of a solvent -- water or coffee. Only when a successful pairing is made can the solute dissolve into the solvent. To increase the rate at which a solute dissolves, you must increase the rate at which molecules within the solute can encounter and subsequently pair with molecules within the solvent.
The rate of dissolving would be temperature dependent.
Heating or stirring will normally increase the rate at which a soluble solid dissolves in liquid. Heating will also normally increase the amount of solute that can be retained in solution.
The smaller the particle the faster it dissolves. This is because the process by which a solute dissolves takes place at the surface of the solvent. That means the larger the surface area of a particle or solute, the faster the solute will dissolve.
Increasing the pressure over a solid solute has virtually no effect on the rate that it dissolves. Stirring and increasing the temperature are the best methods for increasing the rate at which a solid solute dissolves.
Shaking affects the rate at which a solute dissolves because it increases the molecular activity of the solute within the solvent. When the molecular activity is increased, the rate of dissolving is also increased.
It increases the rate at which the solute dissolves.

Not necessarily just changing the surface area causes the rate to change. Changing the ratio of surface area volume changes the rate at which a solute dissolves in a solvent. If the surface area is larger and the volume of a solute is smaller or the same, then the rate at which the solute dissolves in a solvent increases. If the surface area is smaller and the volume of the solute is larger or the same, then the rate at which the solute dissolves in a solvent decreases.

Stirring increases solution ratestirring brings fresh parts of the solvent into contact with the solute and particles are forced to connect. (http://en.wikipedia.org/wiki/Rate_of_solution)

The most usual factors that affect the speed at which something dissolves are the temperature of the solvent, and any stirring of the solution that is being done. The relative quantity of solvent compared to solute is also an important factor, since there is only so much solute that will dissove before the solution is saturated.
