When ice starts melting from 0°C to 8.5°C, its density will:
Show Hint
Water exhibits maximum density at 4◦C, a property crucial for the survival of aquatic life in colder regions.

- Remain constant
- First increase, then decrease
- First decrease, then increase
- Decrease only
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
- At 0°C, ice starts to melt, and the density of water increases as it transitions to the liquid phase.
- Between 0°C and 4°C, the density of water continues to increase due to molecular arrangement becoming more compact.
- Beyond 4°C, the density begins to decrease as the water expands with temperature.
- Thus, between 0°C and 8.5°C, the density of water first increases and then decreases.
