full_question: In Flory-Huggins theory, the enthalpy change associated with this phenomenon is proportional to the interaction parameter chi times kT times the lattice volume fraction phi-sub-2. This phenomenon will occur as concentration increases beyond the Plait point, and does not occur inside the dome on a ternary phase diagram. A paradox named for this process is related to the Gibbs paradox. The increase in entropy due to this process is equal to negative the number of moles times R, times the sum over components of mole fraction times log of mole fraction. A magnetized bar does this process within lab glassware. In an ideal solution, this process evolves no heat. For 10 points, name this process which is used to make a liquid's concentration more homogeneous, by adding an impeller or stirrer.

raw_answer: mixing [accept stirring until "stirrer" is read; anti-prompt on "dissolving" or "solvation"]
