Assertion (A): The increasing pressure on water decreases its freezing point.
Reason (R ):The density of water is maximum at `273 K`.

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:
C
Assertion : As we increase pressure, the freezing point of pure water decreases because more energy is required to bring back the molecules together in a solid structure.
Reason : Density of water is maximum at `4^(@)C` or `273+4=277K`.
