Match the Column: Physical Properties of Milk and Their Measurement Units/Instruments
Match the column:
| TABLE-I (Property) | TABLE-II (Instrument / Unit) |
|---|---|
| 1. Viscosity of milk | a. Lactometer |
| 2. Refractive index of milk | b. Hydrometer |
| 3. Density of milk | c. Dyne cm⁻¹ |
| 4. Specific gravity of milk | d. Zeiss apparatus |
| 5. Surface tension of milk | e. Centipoise |
- 1-e, 2-d, 3-b, 4-a, 5-c — Correct Answer
- 1-a, 2-b, 3-c, 4-d, 5-e
- 1-e, 2-a, 3-b, 4-d, 5-c
- 1-c, 2-d, 3-b, 4-a, 5-e
Explanation:
Correct Answer: 1-e, 2-d, 3-b, 4-a, 5-c
The correct matching of milk physical properties with their instruments/units is:
- 1. Viscosity → e. Centipoise (unit of viscosity; whole milk ~1.5–2.0 centipoise at 25°C)
- 2. Refractive index → d. Zeiss apparatus (Zeiss Refractometer; value: 1.344–1.348 at 20°C)
- 3. Density → b. Hydrometer (at 20°C)
- 4. Specific gravity → a. Lactometer (Quevenne Lactometer at 15.6°C)
- 5. Surface tension → c. Dyne cm⁻¹ (unit; value ~54.5 dyne/cm at 20°C)
