Doubt from Gaseous state

14 d. and 15 c ?

Solution

See

See for 14. In A Co2 will be in gaseous state because the temperature of A is greater than the given sublimation temperature and N2 will also be in gaseous state because the temp of A is greater than the given boiling temperature of N2 and H20 at 27°C is liquid

But in container B temperature is -73°C so h20 will become solid and in the question it is given to neglect the volume of solid so i think D should be the answer

And 15
