What CHEMICAL change happens when a jet flying at high altitudes makes that white trail behind it?

when you see a high flying jet have that white trail behind it .....scientifically...JUST wondering .....

1. This isn't a scientific explanation, but it's the reaction of the heat off the engines condensing the colder air it's going through....kinda like steam..
2. It's both a chemical and a physical change. Whenever you completely combust a hydrocarbon fuel, you get two main products..... carbon dioxide and water vapor The water vapor is made in a chemical reaction (burning) inside the jet engine. It's in the form of high temperature steam, though. Once it expands in the high altitude cold air, though, it instantly drops to subzero temperatures. The humid exhaust products condense water vapor to tiny crystals of ice we see as the vapor trail.
3. When you burn a fossil fuel with adaquate oxygen you will get water and carbon dioxide as a byproduct. The water produced by the exhaust gas is what you see as the "con" trail, or condensation trail.
4. Chemtrails make a thick long white line in the skies. hunt up the topic Chemtrails, alot of info.
5. THe trails are NOT caused by exhaust. They are caused by the compression of the air by the wing & fuselage.
6. the white trail is not a chemical but rather physical phenomenon. the air the eject is ionised and ions tends to attract water molecules and cause them to condense, similar to a diffusion cloud where radiation ionise the air and alcohol vapour condenses and forms white trails
