Mar 30,  · Rather, the white smoke created in their wake is condensation-based contrails. To recap, airplanes leave behind a trail of white smoke due to the mixing of hot and humid air with cool and dry air. It’s essentially the same phenomenon that occurs when you exhale on a cold winter day. Jul 06,  · Airplanes or jets leave a white trail of smoke behind them, which you mostly see in the sky. It is the hot, humid exhaust that releases from the airplane gets mixed with the atmosphere, due to lower vapor pressor and temperature at high altitudes. and then the exhaust gas. Apr 15,  · Vapour trails, or Contrails, are formed when hot, humid and high pressured AIR (not fuel or chems) from an aircraft engine is mixed with the surrounding air that is at a low temp and pressure.
Jul 06,  · Airplanes Jet Planes Remote Control 75 or jets leave a white trail of smoke behind them, which you mostly see in the sky. It is the hot, humid exhaust that releases from the airplane gets mixed with the atmosphere, due to lower vapor pressor and temperature at high altitudes. and then the exhaust gas. Some planes in the sky leave trails that persist and spread, and other planes, in the same sky, leave short-lived trails, or no trails at all. These trails are actually called contrails, short for “condensation trails”. They are not smoke from the engines, they are formed when the water in jet engine exhaust (and there’s quite a lot of it, like car exhaust on a cold day) mixes with wet cold air and condenses and freezes into . They are an artificial cloud formed by aircraft. They're called contrails, which is a shortened version of the phrase “condensation trail." When a jet engine burns fuel, it produces exhaust and it has H2O molecules! When Jet Planes Release Treatment an aeroplane is flying above 25, feet, the outside temperature will be so cold (In minus degree).
