Question

Statement 1: Ammonia gas turns into liquid at 6 atm pressure and 10${}^o$C temperature.​
Statement 2: The vapour density of ammonia is less than that of air. ​

• A. Both Statement (1) and (2) are correct.​
• B. Statement (2) is correct and (1) is incorrect.​
• C. Both Statement (1) and (2) are incorrect.​
• D. Statement (1) is correct and (2) is incorrect.​

Answer 1

The correct option is A Both Statement (1) and (2) are correct.​

Ammonia is compressible at 6 atm pressure and 10${}^o$C temperature, so it turns into liquid at this condition.
Vapour density is defined as the density of a vapour in relation to that of hydrogen. The vapour density value of ammonia is 8.5 and that of air is 14.4.

So both the statements are correct.

The correct answer is option (c).
