Carbon monoxide and other left overs from combustion. However, the trail you see behind a plane flying high up is called the contrail, and it consists of water vapor that freezes behind the plane.
When water in the ocean is heated by the sun it turns into water vapour and evaporates, however it leaves the salt behind as it is made of separate molecules.
...made his way to the center, leaving a trail behind him using the twice of Daedalus. Once in the middle, he slayed the Minotaur with the sword of his father, then followed his own trail back out.
The white trail you see behind an airplane in the sky is called a contrail. It's an artificial cloud made by the exhaust of jet aircraft or from the wingtips.
The water vapour condensed on the windows. The vapour rising off the acid made me choke.
Water Vapour is a colourless, odourless gas which is made of tiny water droplets.

I believe it's a combination of fuel exhaust and rapid compression of the moisture in the atmosphere due to the speed of the plane.ANSWER:It is from the hot exaust from the airplanes engines hitting the low pressure cold air in the upper atmosphere. It causes condensation and makes a cirrus cloud in a long line behind the plane. AnswerWhat is happening is that a combustion byproduct (either of a jet or piston engine), water, is condensing. Maybe even freezing. After all, atmospheric conditions up high usually include very cold air. When conditions are right, the condensate trail can be seen forming a short distance behind the plane. That's not due to compression. When we "see our breath" on a cold day, we are seeing the water vapor in our breath cooling and condensing.
The white gas emitted from planes is actually water vapor that forms from the combustion of jet fuel in the engines at high altitudes where the air is extremely cold and humid. This water vapor quickly condenses into tiny ice crystals, forming the white trails known as contrails.
Basic answer is water vapour from the combustion of the hydrocarbon fuel burnt in the engine. The low temp at high altitude causes the vapour to condense - so it is a man made cloud.All hydrocarbon fuels burn in air (combining with oxygen) to produce water (hydrogen oxide) and carbon dioxide.
A pencil line is a mark made by a pencil when it is pressed against a surface, leaving behind a trail of graphite. It is usually used for drawing or writing.
