When the temperature of water rises from `0^(@)C` to `10^(@)C`,the density of water

A

decreases gradually.

B

decreases up to `4^(@)C` and then increases.

C

increases up to `4^(@)C` and then decreases.

D

increases gradually.

Text Solution

Verified by Experts

The correct Answer is:
C
Density of water is maximum at `4^(@)C` du to anomalous expansion of water. Hence, when the temperature of water is raised from `0^(@)C` to `10^(@)C`, the density increases up to `4^(@)C`, then decreases gradually.
