Reducing particle size results in an increase in surface area. The increase in surface area allows more solvent (water) molecules to interact with the substance, and this increases the rate at which that substance dissolves.
It exposes more of the solute surface to the water molecules.
As the particle size gets smaller, the surface area increases, and as the surface area increases, the ease with which water can hydrate the particles increases. When it is easier for water to hydrate the molecules, this increases the speed at which the solute dissolves.
It exposes more of the solute surface to the water molecules.
no, it will not, in a compressible gas, the contents will increase in density, thus reducing its buoyancy. in an incompressible liquid or solid, no noticeable change will occur.

For the amount of material in the particle the surface area of a small particle is greater than a larger particle. Said another way, the surface area per unit volume is greater for a smaller particle. Dissolving speed is related to the surface area. Therefore a smaller particle dissolves faster than a larger particle.
1) increase the solvent's temperature 2) add more solvent 3) stir (have the solvent and solute meet together more instead of letting the solute rest at the bottom of the solvent)

Acids such as hydrochloric acid or sulfuric acid can dissolve iron oxide. Strong reducing agents like hydroxylamine can also dissolve iron oxide by reducing it to a soluble form.
Increasing the force applied to push the wheelbarrow or reducing the mass of the load in the wheelbarrow will increase its acceleration. Additionally, reducing friction between the wheelbarrow and the ground can also increase its acceleration.
