Question 5 • AA-F26 Physical Science

Which describes how a centrifuge separates a mixture?

Answer
A
It spins a sample to separate based on density.
B
It spins a sample to separate based on boiling point.
C
It heats a sample to separate based on density.
D
It heats a sample to separate based on boiling point.

Explanation

A centrifuge spins a mixture rapidly, causing denser components to move outward and separate from less-dense components. It does not separate substances by heating them or by their boiling points. Therefore, the correct choice is “It spins a sample to separate based on density.”
