dissolving | Forming a solution by combining two ore more things together |
solute | something that gets dissolved |
solvent | something that does the dissolving |
why did the sugar dissolve in water? | because sugar particles are more attracted to the water particles |

What causes something to dissolve faster | increasing temperature |
what causes something to dissolve faster | decreasing particle size |
what causes something to dissolve faster | stirring or shaking |
what causes something to dissolve faster | increasing pressure |
why does increasing the temperature cause something to dissolve faster | The particles will move faster and the solvent will carry the solute particles away faster |
Why does decreasing the particle size make something dissolve faster | When the solute is in smaller pieces, there is more surface area where dissolving can occur |
Why does stirring or shaking make something dissolve faster | it moves the solute particles around so that they are closer to the solvent particles. |
