The solute particles increase the intermolecular forces between solvent molecules.

The solute particles decrease the kinetic energy of the solvent molecules.

The solute particles occupy some surface area, reducing the solvent's ability to evaporate.

The solute particles react with the solvent molecules, reducing the amount of solvent available.
