Contrails are due to the atmospheric conditions, temprature and wind ( still).The exhaust from the engine freezes quickly under certain conditions and above 30,000 feet, which you see as trail of smoke frozen. Some times due to fuel is injected at the end of turbine to reduce the landing weight. this can also cause white line behind aipcraft.
Contrails are the result of both exhaust fumes (jet fuel is similar to diesel fuel) and the effects of extremely hot exhaust gases reacting to the significantly colder atmospheric air.

There is a white moon and star and there's a green backround behind the moon and the star. On the right side of the flag there is a strip of white.

for white reducing
When ice evaporates, it leaves behind a white residue due to the minerals and impurities present in the water that form a thin layer on the surface as the water evaporates.
The white residue left behind by tap water is typically caused by minerals such as calcium and magnesium that are present in the water. When the water evaporates, these minerals can form a white, chalky residue on surfaces.
Water can leave behind white residue when it evaporates and leaves behind minerals like calcium and magnesium. This residue is known as hard water stains and is commonly seen on surfaces like glass and metal.
The white residue that forms when boiling water is caused by minerals, such as calcium and magnesium, that are left behind as the water evaporates.

The white residue from water is caused by minerals, such as calcium and magnesium, that are left behind when the water evaporates. This residue is commonly known as limescale or mineral deposits.
