Reason- It is proper to regard the gaseous state of ammonia as vapours.​

Answer 1

Answer 2

Answer:

$\boxed {\boxed{ { \red{ \bold{ \underline{I'M \: THE\: DEVIL\: :- \: THE\: LUCIFER }}}}}}$

Explanation:

(b) Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A).

Ammonia is always in the gaseous state (at room temperature also)

But the term vapor is used when a substance at room temperature is solid or liquid and changes to vapor due to change in temperature.
