Answer

Answer:

increase the temperature of the solution and add more salt

Explanation:

Step1: Understand solubility and temperature

The solubility of salt (sodium chloride) in water generally increases with increasing temperature.

Step2: Make a supersaturated solution

By increasing the temperature, more salt can dissolve in the water. Then, if we slowly cool the solution (without disturbing it), the solution can hold more salt than it would at the lower temperature under normal conditions, creating a supersaturated solution. Adding more salt at higher temperature is the key step here. Decreasing temperature (option 2) would lower solubility. Pressure (options 3 and 4) has a negligible effect on the solubility of solids (salt) in liquids (water) compared to temperature for this context.
