Question

Cream can be separated from milk using the centrifugal method because:

• A. cream is lighter than milk
• B. cream is heavier than milk
• C. cream floats over milk
• D. the cream is lighter than milk and comes over it

Answer 1

The correct option is D

the cream is lighter than milk and comes over it

Cream is lighter than milk, and when churned, it rises over milk and can be collected. Centrifugal force is the force that seems to make things shoot outward when they go round in a circle, and this causes the separation of cream from milk.
