The density of water is maximum at:

A

`4^(@)C`

B

`gt 4^(@)C`

C

` lt 4^(@)C`

D

`10^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
A

When cooled from room temperature liquid water becames dense, as compared with other substances, but at approximately `4^(@)C(39^(@)F),` pure water reaches its maximum density. If it is cooled further, it expands to become less dense.
