Question

1. match each method to its effect:

a. stirring
b. heating
c. crushing

1. adds energy to particles
2. moves solute around faster
3. increases surface area

Explanation:

• For stirring (a): Stirring helps in moving the solute particles around faster in the solvent, so it matches with "Moves solute around faster" (2).
• For heating (b): Heating provides energy to the particles, increasing their kinetic energy, so it matches with "Adds energy to particles" (1).
• For crushing (c): Crushing a solute into smaller pieces increases its surface area exposed to the solvent, so it matches with "Increases surface area" (3).

Answer:

a. Stirring - 2. Moves solute around faster
b. Heating - 1. Adds energy to particles
c. Crushing - 3. Increases surface area
