How does the abundance of atmospheric nitrogen balance the combustion effect of oxygen?
Answer and explanation
Correct answer: It dilutes oxygen and keeps combustion intensity controlled
The governing concept is the effect of atmospheric composition on combustion. Oxygen supports oxidation, while nitrogen is comparatively unreactive under ordinary atmospheric conditions and forms most of the air. Its large proportion dilutes oxygen, so fuels do not burn as fiercely as they would in nearly pure oxygen. Option A is correct; nitrogen does not remove all oxygen, create fuel-free fire or turn water vapour into a combustion gas.
