Many race car teams use nitrogen instead of air in their tires. What could be the possible reason/ reasons behind this?
1. In comparison to air, nitrogen is less reactive.
2. Nitrogen pressure is more consistent than normal air pressure
3. Water causes normal air to be inconsistent in its rate of expansion and contraction
Choose the correct option from the codes given below:

Answer: [D] 1, 2 & 3

All are correct statements. Kindly note that Nitrogen is less reactive but it is not an inert gas because it forms nitric oxide and nitrogen dioxide with oxygen, ammonia with hydrogen, and nitrogen sulfide with sulfur.
