Statement-1 : Liquid `NH_(3)` is used for refrigeration.
Statement-2 : Enthalpy of vapourisation of ammonia is very large.

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
Liquid `NH_3` is used for refrigeration is true and it is due to the fact that is vaporises quickly and for vaporisation it takes up heat and cool the refrigerator. Hence assertion and reason both are true.
