Boiling Point of Milk
The boiling point of milk ranges from:
- 100–101°C — Correct Answer
- 99–100°C
- 101–102°C
- 102–103°C
Explanation:
Correct Answer: 100–101°C
The boiling point of milk ranges from 100°C to 101°C (average ~100.5°C), which is slightly higher than that of pure water (100°C at sea level), due to the dissolved solutes in milk.
Physical Properties of Milk — Key Values
- Boiling point: 100–101°C (average 100.5°C) ✔
- Freezing point: −0.535°C to −0.550°C
- Melting point of milk fat: 33–35.5°C
- Specific gravity (cow): 1.028–1.030
- pH of cow milk: 6.4–6.6
Recknagel Phenomenon
The specific gravity of freshly drawn milk is low and increases by 0.001 as time advances — this is known as the Recknagel phenomenon.
