Ambient air consists of many gasses, but of that mix, only 19% of it is oxygen. Many applications will require a higher percentage than the 19%. That's where Concentrated Oxygen fills the need.Concentrated Oxygen refers to oxygen which is a minimum of 90% pure with moisture removed to a -100 deg F dew-point.It can be produced from an oxygen concentrator or delivered in a pressurized cylinder bottle.mbient air consists of many gasses, but of that mix, only 19% of it is oxygen.

Globally, it doesnât sound like much â just 0.049 millimetres per year â but if all the sea ice currently bobbing on the oceans were to melt, it could raise sea level by 4 to 6 centimetres. Fresh water, of which icebergs are made, is less dense than salty sea water. So while the amount of sea water displaced by the iceberg is equal to its weight, the melted fresh water will take up a slightly larger volume than the displaced salt water. This results in a small increase in the water level.
Sea ice growth and melt is a direct result of thermal energy. When cold air cools the ocean by drawing heat from the water through conduction, ice begins to form. As the ocean temperature nears the freezing point, the water density increases and the water sinks.Warmer water that replaces it must also be cooled.n this way, more than just the surface of the ocean must reach the freezing point before ice can form. 9. Once the ice begins to grow, it acts as an insulator between the ocean and atmosphere, slowing down conduction, and also as a barrier from solar radiation, preventing thermal energy transfer by radiation.
