Why does increasing the temperature generally increase the solubility of a solid in a liquid?

• A. It increases the pressure on the solute particles.
• B. It decreases the volume of the solvent, allowing more solute to dissolve.
• C. It decreases the kinetic energy of the solute particles.
• D. It increases the kinetic energy of the solvent molecules, allowing them to interact more effectively with the solute.

Answer: (D)
