Hi guys today we are going to talk about the white trail formation during the winter, when an aeroplane flies.
To understand this phenomenon we must be aware of the combustion process taking place at the time of working of engine.
During the combustion process, carbondioxide and water vapours are the major products.
The water vapours which come out of the exhaust of aeroplane are directly released into the air .
The air in summer is dry or the temperature is high which do not let the vapours condense.
But during winters the atmosphere is cold and as soon as the vapours are released into the air, they condense and thus we can see the foggy trail behind the aeroplane.
