Bombardier beetles are ground beetles (Carabidae) in the tribes Brachinini, Paussini, Ozaenini, or Metriini—more than 500 species altogether—which are most notable for the defense mechanism that gives them their name: when disturbed, they eject a hot noxious chemical spray from the tip of the abdomen with a popping sound.
Brachinus texanus is a species of ground beetle in the genus Brachinus ("bombardier beetles"), in the family Carabidae ("ground beetles"). [ 1 ] [ 2 ] [ 3 ] It is found in North America. Like other bombardier beetles, it can spray a boiling, corrosive liquid from its abdomen if provoked, and as such should not be handled.
Liquid oxygen has a clear cyan color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. [2] Liquid oxygen has a density of 1.141 kg/L (1.141 g/ml), slightly denser than liquid water, and is cryogenic with a freezing point of 54.36 K (−218.79 °C; −361.82 °F) and a boiling point of 90.19 K (−182.96 °C; −297.33 °F) at 1 bar (14.5 psi).
BLEVE–fireball, 2008 Toronto propane explosion The following is a list of boiling liquid expanding vapor explosion (BLEVE) accidents. It shows whether the accident occurred during dangerous goods transportation or at a fixed facility, the accident origin (e.g., storage, process reactor, rail tank car, tank truck), the material involved, its amount, the number of fatalities, and whether a ...
The bombardier beetle is unusual by using a violent exothermic chemical reaction to launch a boiling noxious chemical spray in a rapid burst of pulses from special glands in its abdomen, accompanied with a popping sound. The Anthia (oogpister beetle) will fire formic acid at
Medical use liquid oxygen airgas tanks are typically 2.4 MPa (350 psi). [citation needed] All equipment coming into contact with high pressure oxygen must be "oxygen clean" and "oxygen compatible", to reduce the risk of fire. [3] [4] "Oxygen clean" means the removal of any substance that could act as a source of ignition. "Oxygen compatible ...
Explosive boiling can be best described by a p-T phase diagram. [3] Figure on right shows a typical p-T phase diagram of a substance. The binodal line or the coexistence curve is a thermodynamic state where at that specific temperature and pressure, liquid and vapor can coexist.
