To help Jill dissolve the 30 grams of substance X in water more quickly, she should consider the following method:
She should crush X crystals to find powder before adding them to the water.
Crushing the crystals increases the surface area of the substance, allowing it to dissolve faster when added to water. While increasing the temperature can also help dissolve materials faster, crushing the crystals is a direct approach that often yields immediate results in terms of solubility.
So, the best choice from the options provided is:
- She should crush X crystals to find powder before adding them to the water.
