Question: 9
The gas used to inflate the tyres of an aircraft is-
- Hydrogen
- Nitrogen
- Helium
- Neon
Show/Hide Explanation
Correct Answer: B
None
Sol. Nitrogen gas is used in the types of an aeroplane. This is because the nitrogen gas does not support combustion and can assist in preventing wheel fire when the aircraft lands (braking and high speed can produce dangerously high temperatures) unlike in oxygen. There are other benefits but effectively it is being the lowest cost gas that does not support combustion. It is preferred in comparison with the oxygen because nitrogen does not contain water. Thus, when the plane is at more height, gas in tyres does not get frozen.
