Assertion : The density of water remains...

Assertion : The density of water remains constant as it is cooled from room temperature untill its temperature reached `4^(@)C`.
Reason : Below `4^(@)C`, the density increases.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true and reason is not the correct explanation of assertion.

C

If assertion is true and reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
D
The volume of water decreases when water is cooled from room temperature, until its temperature reaches `4^(@)C` and hence density increases. Below `4^(@)C`, the volume increases and therefore, the density decreases.
