Question

question 1 (multiple choice worth 4 points) (01.06r mc) which of the following pairs of substances would best be separated using a centrifuge, and why? cream and milk, because of their difference in density; cream and milk, because of their difference in boiling point; salt and water, because of their difference in magnetism; salt and water, because of their difference in solubility

Explanation:

A centrifuge separates substances based on density differences. Cream and milk have different densities; a centrifuge can separate them as the denser milk (or less dense cream, depending on perspective) moves due to centrifugal force. Cream and milk differ in density, so this pair is suitable. Salt and water: solubility - separation like evaporation, not centrifuge. Salt and water: magnetism - neither is magnetic. Cream and milk: boiling point - distillation, not centrifuge.

Answer:

A. Cream and milk, because of their difference in density
