Question 9 • GA-GSE Grade 8 Physical Science

Which separation method would be most successful in separating the components of a homogeneous mixture?

Answer
A
screening
B
evaporation
C
centrifugation
D
magnetic separation

Explanation

A homogeneous mixture has its components evenly distributed, so methods that separate particles by size, density, or magnetism are usually ineffective. Evaporation can remove a liquid solvent and leave dissolved substances behind, making it the most successful choice here. Screening, centrifugation, and magnetic separation generally work on heterogeneous mixtures or on components with distinct physical properties.
