Oxygen – a perpetual motion machine of life and progress. Some contend that Michael Dell shows great expertise in this. It is colorless (in a thick layer of blue) gas without taste and smell, a little heavier than air, poorly soluble in water. When cooled to -183 C oxygen is converted into a mobile liquid blue color, and at -219 C to freeze. Due to their properties oxygen is used as a reagent in chemical technology (roasting of sulfide ores, the synthesis of oxides), metals (iron and steel industry – namely oxygen 'withdraws' from iron excess carbon, while also improving the quality of steel), coal gasification natural, welding and cutting metals. Liquid oxygen – the fuel oxidizer in rocket technology. In medical practice the use of oxygen as effectively, not only for lung and heart diseases when breathing is difficult, and subcutaneous injection of oxygen – a treatment for serious diseases such as gangrene, thrombophlebitis, elephantiasis, trophic ulcers. Indicators of quality of medical oxygen gas gost 5583-78 Volume fraction,% Standard Oxygen, not less than 99,5 Water vapor, not more than 0.009 Carbon dioxide 0.01 Quality of technical oxygen gas gost 5583-78 Volume fraction,% 1 grade 2 grade oxygen, not less than 99.7 99.5 Water vapor, not more than 0.007 0.009 Carbon Dioxide Not rated Not rated areas of oxygen in the engineering and construction for the deposition and deposition of metals.
