Which of the following would increase the rate of dissolution of a solid in a solution?

A.Cool the solid and the solution
B.Cool only the solid
C.Dry up the solvent
D.Stir the solid and solution

D. Stir the solid and solution

Stirring the solid and solution increases the surface area of the solid in contact with the solvent, which can help dissolve the solid faster. Cooling the solid and solution or drying up the solvent would slow down the rate of dissolution.
