Verified step by step guidance

Understand that the rate at which a substance dissolves in a solvent depends on factors that increase the interaction between solute and solvent particles.

Recognize that increasing the temperature of the solvent generally increases the kinetic energy of the molecules, causing them to move faster and interact more frequently, which speeds up dissolution.

Note that using a solvent with lower polarity usually decreases solubility for polar solutes, so it does not typically make a substance dissolve faster.

Understand that decreasing the surface area of the solute reduces the exposed area for solvent interaction, which slows down the dissolution process; increasing surface area speeds it up.

Realize that reducing stirring or agitation decreases the movement of solvent around the solute, slowing dissolution; increasing stirring helps dissolve substances faster.
