Hydrazine is an inorganic compound with the chemical formula N 2 H 4.It is a simple pnictogen hydride, and is a colourless flammable liquid with an ammonia-like odour.Hydrazine is highly hazardous unless handled in solution as, for example, hydrazine hydrate (N 2 H 4 ·xH 2 O).
In freeze sprays, a controlled amount of this cooling is useful. Uncontrolled cooling, however, can result in freeze burns to the skin. According to controlled laboratory experiments, the gas from a typical deodorant spray can reduce skin temperature by up to sixty degrees Celsius. [2] The form of injury is freezing of the skin, a type of ...
A mix of hydrazine and UDMH has a far lower freezing point due to freezing-point depression. In addition, UDMH is a more stable molecule; this reduces the risk of pure hydrazine decomposing unexpectedly, increasing safety and allowing the blend to be used as a coolant in regeneratively cooled engines.
Hydrazines (R 2 N−NR 2) are a class of chemical compounds with two nitrogen atoms linked via a covalent bond and which carry from one up to four alkyl or aryl substituents. . Hydrazines can be considered as derivatives of the inorganic hydrazine (H 2 N−NH 2), in which one or more hydrogen atoms have been replaced by hydrocarbon grou
Also, if you touch dry ice to your skin for very long, you will freeze your skin and get what is usually called a burn (because it hurts just like one, and involves subcutaneous tissue damage just like one, even though it's caused by extreme cold rather than extreme heat). —Steve Summit 01:38, 9 February 2007 (UTC)
