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 `(A)` and `(R )` are correct, and `(R )` is the correct explanation of `(A)`.

B

If both `(A)` and `(R )` are correct, but `(R )` is not the correct explanation of `(A)`.

C

If `(A)` is correct, but `(R )` is incorrect.

D

If `(A)` is correct, but `(R )` is correct.

Text Solution

Verified by Experts

The correct Answer is:
C
Since `P prop (1/T)`, therefore on increasing the pressure, the freezing temperature decreases.
