Liquid oxygen has a clear cyan color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. [2] Liquid oxygen has a density of 1.141 kg/L (1.141 g/ml), slightly denser than liquid water, and is cryogenic with a freezing point of 54.36 K (−218.79 °C; −361.82 °F) and a boiling point of 90.19 K (−182.96 °C; −297.33 °F) at 1 bar (14.5 psi).
The term "oxygen tank" is commonly used by non-divers; however, this is a misnomer since these cylinders typically contain (compressed atmospheric) breathing air, or an oxygen-enriched air mix. They rarely contain pure oxygen, except when used for rebreather diving, shallow decompression stops in technical diving or for in-water oxygen ...
A gas duster, also known as tinned wind, compressed air, or canned air, is a product used for cleaning or dusting electronic equipment and other sensitive devices that cannot be cleaned using water. This type of product is most often packaged as a can that, when a trigger is pressed, blasts a stream of compressed gas through a nozzle at the top.
To use oxygen bleach to clean glass shower doors, pour a premade powder oxygen bleach solution or liquid oxygen bleach into a spray bottle for easy application. Spray the glass shower door ...
Most humans can function at rest with an oxygen level of 15% at one atmosphere pressure; [1] a fuel such as methane is combustable down to 12% oxygen in nitrogen. A small room of 10 meter 3 has 2.08 meter 3 (2080 liters) or 2.99 kg of oxygen which would occupy 2.62 liters if it was liquid. [2]
This type of aeration has a very high oxygen transfer efficiency (OTE), sometimes as high as 15 pounds of oxygen / (horsepower * hour) (9.1 kilograms of oxygen / (kilowatt * hour)). [4] On average, diffused air aeration diffuses approximately 2–4 cfm (cubic feet of air per minute) (56.6-113.3 liters of air per minute), but some operate at ...
Medical use liquid oxygen airgas tanks are typically 2.4 MPa (350 psi). [citation needed] All equipment coming into contact with high pressure oxygen must be "oxygen clean" and "oxygen compatible", to reduce the risk of fire. [3] [4] "Oxygen clean" means the removal of any substance that could act as a source of ignition. "Oxygen compatible ...
The amount of oxygen is more difficult to calculate, as it is derived from two sources, the added oxygen and the air top-up. However, all of the nitrogen is provided by the air top-up, so the partial pressure of the nitrogen is calculated in a similar way as for helium, which allows the pressure of the air to be calculated, assuming nitrogen to ...
