An example of conduction is through metal. Without aggressive intervention by the flight crew, a fire on board an aircraft can lead to the catastrophic loss of that aircraft within a very short space of time. Some smaller fires or bonfires may stay pale depending on the material burned. Oppositely, flammables are more likely to form vapours in normal work environments, because their flash points are lower. News: Please keep the forum spam free. Fire is a rapid oxidation process that spreads . Washover fan deposits are part of a much larger system of highly heterolithic barrier and shoreline-margin deposits which form notoriously hard to produce hydrocarbon reservoirs. Flammable and combustible materials will generate vapours when exposed to a temperature at, or above, its flash point, which can easily ignite when exposed to an ignition source. Smoke isnt a gas, though it behaves, mainly, like a gas, it does contain solids and liquids as well. Originally all barbecue and grilling was done with logs of wood as the sole fuel source.
