Question

Milk is an example of

• A. Emulsion
• B. Suspension
• C. Gel
• D. True solution

Hint:

An emulsion is a colloidal system where both the dispersed phase and dispersion medium are liquids.

Answer 1

The Correct Option is A

Step 1: Understand what milk consists of. Milk is a mixture of fat droplets dispersed in water.
Step 2: An emulsion is a type of colloid in which one liquid is dispersed in another liquid.
Step 3: In milk, fat (liquid) is dispersed in water (liquid), forming a liquid–liquid colloid.
Step 4: Therefore, milk is an emulsion.
Step 5: The other options are incorrect because:

Suspension has large particles that settle down.
Gel is a semi-solid system.
True solution has particles of molecular size.
