The jet contrails are exaust from the jet engines, which is mostly carbon dioxide and water vapour.
smoke
The white trail is called a contrail which is short for condensation trail. The fumes that are emitted from the engines of planes contain a large amount of water vapours. When the plane is at a high altitude, the temperature can be low enough to freeze the water vapour into tiny crystals which we see as a white trail. The trail disappears when the water evaporates.
When you see a white trail behind an airplane, that is what is known as a contrail, short for condensation trail, and it is composed of water vapor, not smoke. This condensation happens because the hot exhaust of the plane's engine meets the colder surrounding air and the mixture of cold and hot air is a sort of miniature weather front.
The white line left behind a plane is called a contrail, short for "condensation trail." It is formed when hot, moist engine exhaust mixes with cold air at high altitudes, causing the water vapor to condense and freeze into ice crystals.
jet plains have a white trail behind because of the moisture for some time. in higher layer of atmosphere where there is hot air to disturb it. this trail is suspeded for a long time
Water vapour.
Yes sometimes. The white trail is called a 'contrail' and is caused when water in the air through which the plane is flying condenses out on particles produced from the plane's engine exhaust. Thus any plane with an engine can produce a contrail if the conditions are right.
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.
In geology, an onyx streak may refer to the color trail left behind when the stone is scratched against a rough surface. This streak is often white or colorless, as onyx is a type of chalcedony composed of fine intergrowths of silica minerals.
the government is honeslty trying to posion us.. its called a chem trail.
It's the fuel from the engines.
If you ever see a commercial airliner in flight behind it there will be a white tail folowing it. This is the smoke trail.
