A beaker of water is heated to increase its solubility, and it is saturated with a solid solute compound, such as salt. Then the solution is cooled down and a small salt crystal is dropped into the water.

Answer:

The solid crystal will precipitate.

Explanation:

Solubility indicates how much solid can be in solution without it precipitating and depends on the temperature for most salts or compounds, increasing as the temperature rises.

Therefore, if the beaker is heated, more solid will remain in solution, in this case until saturation (the maximum amount of the solid that can be in solution without it precipitating).

As the temperature drops, the solubility drops, therefore any amount of solid that is added additionally will precipitate.
