Raising solvent temperature causes solvent-solute collisions to become

raising solvent temperature causes solvent-solute collision to become more rapid in the sense that the collision gain more kinetic energy.

Explanation:

When the temperature of a solvent is increased, kinetic energy (motion) is increased. The rate of collision of solvent to solute increases as temperature rises. Solvent to solute collision move rapidly with force when temperature is increased.

Increase in temperature also increase solubility of solute in solvent. As the solvent temperature is increased, kinetic energy will increase, allowing the solvent molecules to move rapidly and weaken/break the intermolecular forces that held the solute molecules together. The breakdown of the intermolecular forces brings about solubility.
