Liquid nitrogen is a compact and readily transported source of dry nitrogen gas, as it does not require pressurization. Further, its ability to maintain temperatures far below the freezing point of water, specific heat of 1040 J ⋅kg −1 ⋅K −1 and heat of vaporization of 200 kJ⋅kg −1 makes it extremely useful in a wide range of ...
Nitro compounds are explosive because although the diatomic form of nitrogen is very stable—that is, the triple bond that holds N 2 together is very strong, and therefore has a great deal of bond energy—the nitro compounds themselves are unstable, as the bonds between nitrogen atoms and other atoms in nitro compounds are weak by comparison.
A chemical weapon agent (CWA), or chemical warfare agent, is a chemical substance whose toxic properties are meant to kill, injure or incapacitate human beings.About 70 different chemicals have been used or stockpiled as chemical weapon agents during the 20th century, although the Organisation for the Prohibition of Chemical Weapons (OPCW) has an online database listing 35,942 chemicals which ...
Since explosives usually contain nitrogen, detection often is based around spotting nitrogenous compounds. As a result, traditional colorimetric tests have a disadvantage: some explosive compounds (such as acetone peroxide) do not contain nitrogen and are therefore harder to detect. [1]
The 2006 transatlantic aircraft plot was a terrorist plot to detonate liquid explosives, carried aboard airliners travelling from the United Kingdom to the United States and Canada, disguised as soft drinks. [1] The plot was discovered by British Metropolitan Police during an extensive surveillance operation. As a result of the plot ...
In the second part, the person in the video cracks an egg open into the liquid and the content solidifies very quickly as you can see after it's taken out. WATCH: See how a GoPro handles a torture ...
Using oil well drilling equipment, injection of liquid nitrogen began on 4 May. It was estimated that 25 tonnes (55 thousand pounds) of liquid nitrogen per day would be required to keep the soil frozen at −100 °C (−148 °F). [18]: 59 This idea was quickly scrapped. [87]
NEW Cooperative, Inc. in Red Oak notified officials Monday, March 11, that a valve on an aboveground tank storing liquid nitrogen fertilizer was left open all weekend, according to a March 28 news ...
