Let me tell you what is the difference between a gas and a vapour. If you like it, please follow me to get more answers...
The substances which originally exists in gaseous state, are called gas, but the substances which originally does not exist in gaseous state but are changed to gaseous state by changing the temperature and pressure are called vapour.
For example, consider water. Water originally exists in liquid state at room temperature. However when we heat it, it changes into steam and we call it water VAPOUR.
Now, consider Bromine. Bromine is liquid at room temperature. However, when it is changed to gaseous state, we call it as Bromine vapour.
Now consider nitrogen dioxide, oxygen, nitrogen.....they are naturally gas...they exist in gaseous state...so they are called gas, not vapour.
