-[[Oxygen]], also known as '''O<sub>2</sub>''', is the basic gas necessary for human survival.  It is is released when smelting certain ore (such as [[Ore_(Gold)|gold]]) or by melting [[Ice_(Oxite)|Oxite]]. It is also produced by plants in [[Hydroponic_Tray|hydroponic trays]] or the [[Hydroponic_Station|hydroponics station]] when they photosynthesize.

-Pure oxygen auto-ignites at 300°C when in [[atmosphere]] at any pressure when [[Volatiles|volatile]] gas is present. This may be caused by activating the [[Welder]], engaging any type of crafting stations working with metal (such as [[Autolathe]]), or using any firearm, either of which will create a local temperature spike and the follow-up chain reaction.

This may be caused by activating a gas-powered [[Welder|welder]], engaging any type of crafting stations working with metal (such as an [[Autolathe|autolathe]]), or using any firearm, either of which will create a local temperature spike and the follow-up chain reaction.
-'''Liquid Oxygen''' can be created by lowering the temperature of Oxygen gas below it's boiling point, or by raising it's pressure above it's condensation point. The boiling point of Oxygen is 90K (-183°C) at 100kPa.
+Oxygen is mainly used in sustaining human life, either in the ambient atmosphere when your helmet is open, or in your suit's oxygen tank. Oxygen's other roles are in the creation of [[Fuel#Gas_Fuel|fuel]], as well as [[Nitrous Oxide]] through the use of a [[Nitrolyzer]].
-== Usage == <!--T:2-->
+== Notes ==
-The main usage is in sustaining your life, either in the ambient atmosphere when your helmet is open, or in your suit's oxygen tank.  Aside from that it is used for combustion in the [[furnace]] and the [[Gas_Generator|gas generator]].
+* When used as oxidizer in rocket fuel, oxygen has a mass of 62.4 mol/kg.
