Answer

Explanation:

Step1: Recall solubility concept

Solubility of sugar in water increases with temperature.

Step2: Analyze rock - candy making

To make rock candy, we start with a saturated sugar - water solution. Heating it allows more sugar to dissolve as solubility increases. Then, cooling the solution causes the sugar to crystallize out as the solubility decreases at lower temperatures.

Step3: Evaluate options

  • Option 1: Heating a saturated sugar - water solution, dissolving more sugar, then letting the solution cool is correct for rock - candy making.
  • Option 2: Waiting for water to evaporate is not the typical way for making rock candy as it may lead to uneven crystal formation.
  • Option 3 and 4: Changing pressure has little effect on the solubility of solids (sugar) in liquids (water) compared to temperature changes.

Answer:

heat a saturated sugar water solution, dissolve more sugar, then let the solution cool
