Why do we regard the gaseous state of water as vapours while that of ammonia as gas ?

Text Solution

Verified by Experts

Only the gaseous states of those substances are regarded as vapours which are liquid at room temperature. Since water is a liquid, its gaseous state is called vapours. However, the gaseous state of ammonia is called gas because it is not a liquid at room temperature.
