Question

Milk is a mixture. Give reasons.

Answer 1

• A mixture is formed when atoms or molecules of the same or different particles combine with each other physically.
• Milk is a mixture of cream and skimmed milk.
• Its constituents can be separated using the technique of Centrifugation.
• Centrifugation is a technique for separating suspended particles from liquids in which the mixture is rotated (or spun) at high speed in a centrifuge.
• On rotation, the cream being lighter starts floating above the skimmed milk, which can be easily poured into another container to separate the constituents.
