What method would you use to separate sand from gasoline?

Filtration (The process of separating liquids and solids)

Explanation:

Filtration works best when the solute isn't dissolved in the solvent. Basically like how you can filter dirt or sand from water. The opposite of this would be if water and sugar where mixed together you cannot unmix this duo with filtration but with the example given you can use the process of filtration to rid the gasoline of sand.

your answer would be “dry”
