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 .
The solar wind's equivalent of a sonic boom in the solar-system plasma medium can accelerate protons up to millions of miles per minute – as much as 40 percent of the speed of light. [ citation needed ] This is a proven source of auroras , but has never yet been shown to be sufficiently forceful and sufficiently abrupt to cause a "boom".
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 .
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 ...
The series of coal dust explosions within a mine rocked the close-knit township and was audible as far as 30 kilometres (19 mi) away. Benxihu Colliery explosion: April 26, 1942: Benxi, Liaoning Manchukuo (now China) coal dust and gas: 1,549: 34% of the miners working that day were killed. This is the world's worst-ever coal-mining accident.
Gas lighting in the historical center of Wrocław, Poland, is manually turned off and on daily.. Gas lighting is the production of artificial light from combustion of a fuel gas such as methane, propane, butane, acetylene, ethylene, hydrogen, carbon monoxide, coal gas (town gas) or natural gas.
Lighting a fart. Fart lighting, also known as pyroflatulence or flatus ignition, is the practice of igniting the gases produced by flatulence.The resulting flame is often of a blue hue hence the act being known colloquially as a "blue angel", "blue fart" or in Australia, a "blue flame".
Apocalyptic fiction is a subgenre of science fiction that is concerned with the end of civilization due to a potentially existential catastrophe such as nuclear warfare, pandemic, extraterrestrial attack, impact event, cybernetic revolt, technological singularity, dysgenics, supernatural phenomena, divine judgment, climate change, resource depletion or some other general disaster.
