Answer 1

$\huge\tt\blue{⚲\:Hello\:Mate}$

Solution : Dinitrogen does not burn or support combustion . Thus N2(g) is used to provide an inert atmosphere during welding and for certain metallurgical processes where oxidation might otherwise occur and for filling electrical lamps.♡

Answer 2

Explanation:

Filling a bulb with an inert gas such as argon or nitrogen slows down the evaporation of the tungsten filament compared to operating it in a vacuum.
