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.

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
