the amount of surface area per a given mass
the temperature at which subtances become a mixture

The best description of solubility is the ability of one substance to dissolve in another.

The best description of solubility is the ability of one substance to dissolve in another. Solubility refers to the capability of a substance, known as the solute, to dissolve in a solvent. This property determines how effectively a solute can be incorporated into a solvent to form a homogeneous solution. The solubility of a substance can vary depending on factors such as temperature, pressure, and the nature of the solute and solvent.
