  2. Gas exchange - Wikipedia

    en.wikipedia.org/wiki/Gas_exchange

    Gas exchange is the physical process by which gases move passively by diffusion across a surface. For example, this surface might be the air/water interface of a water body, the surface of a gas bubble in a liquid, a gas-permeable membrane, or a biological membrane that forms the boundary between an organism and its extracellular environment.

  3. Exploding animal - Wikipedia

    en.wikipedia.org/wiki/Exploding_animal

    The explosion of animals is an uncommon event arising from natural causes or human activity. Among the best known examples are the post-mortem explosion of whales, either as a result of natural decomposition or deliberate attempts at carcass disposal. [1] Other instances of exploding animals are defensive in nature or the result of human ...

  4. Cambrian explosion - Wikipedia

    en.wikipedia.org/wiki/Cambrian_explosion

    The Cambrian explosion (also known as Cambrian radiation [1] or Cambrian diversification) is an interval of time beginning approximately in the Cambrian period of the early Paleozoic, when a sudden radiation of complex life occurred and practically all major animal phyla started appearing in the fossil record.

  5. Gas explosion - Wikipedia

    en.wikipedia.org/wiki/Gas_explosion

    A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. [1] In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas , methane , propane , butane .

    Explosion of unserviceable ammunition and other military items The explosion of the Castle Bravo nuclear bomb. An explosion is a rapid expansion in volume of a given amount of matter associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Explosions may also be ...

[75] 7 April 2020 OneH2 Hydrogen Fuel plant in Long View, North Carolina: An explosion caused significant damage to surrounding buildings. The blast was felt several miles away, damaging about 60 homes. No injuries from the explosion were reported.

  8. Deflagration to detonation transition - Wikipedia

    en.wikipedia.org/wiki/Deflagration_to_detonation...

    The main mechanism of detonation propagation is of a powerful pressure wave that compresses the unburnt gas ahead of the wave to a temperature above the autoignition temperature. In technical terms, the reaction zone (chemical combustion) is a self-driven shock wave where the reaction zone and the shock are coincident, and the chemical reaction ...

  9. Nuclear explosion - Wikipedia

    en.wikipedia.org/wiki/Nuclear_explosion

    A nuclear explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction.The driving reaction may be nuclear fission or nuclear fusion or a multi-stage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion weapon remains a hypothetical device.
