It exposes more of the solid to whatever you want to mix it with so that whatever you are doing, whether it be a physical or chemical change, will take place more rapidly.

Does increasing the surface area of a solid decrease the rate of solution?
no
What will increasing the surface area of a solid do to the dissolving rate of that solid?
It will increase it, as more of the outer surface of the solid is incontact with the liquid that it is dissolving in. :)
How does breaking up a solid speed dissolving in liquid?
By breaking up the solid, you are creating more surface area. Therefore, increasing the surface area will speed up dissolution.
How does surface area of an object affect gravity?
increasing the surface area of reactants in a solid form the speed of reaction is increased the contact between the solid reactants or liquids and gas.
How does the surface area affect the rate of a reaction?
The powdered solid has a greater surface area than the single lump of solid. So the larger the surface area of the solid, the faster the reaction will be. Increasing the surface area of the solid increases the chances of collision taking place between the molecules of reactants, if it is a reaction in liquid or gaseous phase.
How do temperature and increasing surface area affect nuclear decay?
there is no effect of either
How does increasing the surface area of a solid reactant affect the energy of molecular collisions?
Reactions depend on molecular collisions. If a solid reactant is a solid, grinding it into smaller particles will increase the surface area. The more surface area, the faster the molecular collisions, which in turn increases the rate of reaction.
What does increasing the surface area of a solid do to the solution?
When the surface area is higher, it helps to dissolve it in the solution faster.
Why does crushing a solid increase the speed at which the solid dissolves?
ALL reactions (apart from Nuclear) take place on the surface. By crushing the solid you are increasing the surface area and also the SA/Volume ratio. This increased surface area increases the area available for the dissolution reaction.
What does it mean to increase the surface area of a solid?
increase the surface area of a solid means to increase the area of solid
Why does crushing help a solid solute dissolve?
The rate of dissolution of a solid is dependent on the surface area reaction. By crushing the cube, the surface area is greatly increased, thus increasing the rate of dissolution.
What is the surface area of solubility?
There is no such thing as "surface area" of "solubility" since the latter refers to the maximum concentration in the solution of a solid (or liquid) in a liquid. "Surface area", as applied to such a phenomenon is meaningless. However, by *increasing* the surface area of, say, a salt, by grinding it, will increase its solubility. Maybe *that* is what the questioner meant.
