It reacts with other chemicaps a lot faster because there are more particles readily available at one point in time for reactions to occur
increase the surface area of a solid means to increase the area of solid
You increase the surface area
It will increase it, as more of the outer surface of the solid is incontact with the liquid that it is dissolving in. :)
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.
It really depends on what solid you refer to. Basically, the surface area is basically taking a shape's net and finding the area of that.

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.
The surface area increase by a factor of 49.
Superficial expansion is the increase in surface area of 1 meter square area of a solid for rise of temperature, 1kelvin is called the coefficient of surface expansion of material of that solid.
Grinding the solid into a powder increases the surface area and increases the rate of the reaction. Heating it would also increase the rate.
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.
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.
The change in the surface area depends on the shape. The volume will double.
Increased surface area for reaction to occur on
Examples:- increase the temperature- increase the pressure- stir the mixture- grind the solid solute
