Deflagration (Lat: de + flagrare, "to burn down") is a term describing subsonic combustion that usually propagates through thermal conductivity; hot burning material heats the next layer of cold material and ignites it. Most "fire" found in daily life, from flames to explosions, is deflagration. Deflagration is different from detonation, which is supersonic and propagates through shock compression. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Detonation involves a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it. Detonations are observed in both conventional solid and liquid explosives,[1] as well as in reactive gases. The velocity of detonations in solid and liquid explosives is much higher than that in gaseous ones, which allows far clearer resolution of the wave system in the latter.

Name the invasive species?
Weegy: These are lists of invasive species by country or region. [ A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i.e., is not a native species), becomes capable of establishing a breeding population in the new location without further intervention by humans, and becomes a pest in the new location, threatening agriculture and/or the local biodiversity. The term invasive species refers to a subset of those species defined as introduced species, for which see List of introduced species. List of invasive species in Africa List of invasive species in Asia List of invasive species in Australia Invasive species in New Zealand List of invasive species in Europe Invasive species in the British Isles List of invasive species in North America List of invasive species in the Everglades List of invasive species in the Mid-Atlantic region of the United States List of invasive plant species in New Jersey Invasive plants of Wisconsin ] (More)
