37. Why does heating increase the speed at which a solid dissolves? (A) Heating increases kinetic energy of particles, resulting in more effective collisions between solvent and solute. (B) Heating causes particles to decompose, resulting in smaller solute particles that are more easily dissolved in the solvent. (C) Heating increases the ratio of solvent to solute particles, making it easier for solute particles to be distributed among solvent particles. (D) Heating does not affect the speed at which a solid dissolves.
