Assertion : A beaker is completely filled with water at `4^(@)C` . It will overflow, both when heated or cooled.
Reason : There is expansion of water below and above `4^(@)C` .

A

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

B

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

C

If assertion is true but reason is false

D

If the assertion and reason both are false

Text Solution

Verified by Experts

The correct Answer is:
A
Water has maximum density at 4°C. On heating above 4°C or cooling below 4°C, density of water decreases and its volume increases. Therefore, water overflows in both the cases
