- 30. Stirring or shaking a liquid mixture makes its solid particles dissolve faster. Stirring causes the surface of each tiny particle of such substances as sugar, and coffee to be exposed to the water. Substances dissolve faster when the surface of each tiny particle comes in contact with water.
- 31. Crushing a solid solute into smaller pieces makes it dissolve faster. Materials in powder form such as powdered soap and rocky salt dissolve faster than the same materials that are in solid or compact form.
- 32. Heat energy affects how a solute dissolves in a solvent. Heat increases the temperature of the solvent and the solute (such as hot water), causing the particles of such substances as sugar to move faster. As the motion of the solute and solvent increases, a greater chance occur for the solvent and solute to come into contact with each other.
