== Description == 
<blockquote><q>Volatiles is a combustible fuel. It is refined from [[Ice (Volatiles)]]</q> 
'''- Stationpedia'''</blockquote>

'''Volatiles''' or '''H2''' is a combustible gas in the presence of Oxygen and the breathing gas of the [[Zrilian]] species. The main source of Volatiles on most planets is in the form of [[Ice (Volatiles)]] that can be mined on the surface. Volatiles will autoignite at 300 Celcius or above in the presence of [[Oxygen]], and autoignite at 50 Celcius or above in the presence of [[Nitrous Oxide]].

=== Composition ===
Denoted with the name ''Volatile'', it is a homogenous compound made up of Hydrogen, Chlorine and Hydrocarbons. This means that it is poisonous due to the Chlorine, but also combustible due to the Hydrogen and Methane portions and can be turned into [[Water]] with [[Oxygen]] in a [[Kit (Atmospherics) H2 Combustor|H2 Combustor]] that has a self-contained catalyst which helps free the Hydrogen atoms.

Possible compound: CH3Cl (Chloromethane)


== Usage == 
''See also: [[Fuel]]''

Different ratios of Volatiles and Oxygen will produce different temperatures and pressures during combustion. Combustion will create a large amount of Heat, pressure, and [[Carbon Dioxide]]. This reaction is useful inside a [[Furnace]] for smelting ores and creating alloys, but can be catastrophic when inside a [[Canister]] or a room.

Currently as of version v0.1.1089.5513, it is labeled in the atmospheric analyzer as H2, but it is not Hydrogen.<ref>Stationeer's Discord https://discordapp.com/channels/276525882049429515/392785541411635201/393216103284998144</ref>. When burned, it produces heat, [[Pollutant]]s, and [[Carbon Dioxide]] in the following reaction:

2 Volatiles + 1 O2 → 3 [[Pollutant|X]] + 6 [[Carbon Dioxide|CO2]] + 2×Enthalpyvolatiles heat energy

1 Volatiles + 1 [[Nitrous Oxide|N2O]] → 2 [[Nitrogen|N2]] + 2 [[Carbon Dioxide|CO2]] + 2×Enthalpyvolatiles<ref>Cows are evil youtube video https://youtu.be/-nELRhGK1_A?t=890</ref> heat energy

Enthalpy of volatiles is 286000 Joules, this is per amount of Moles of matter.

Since both reactions results in same amount of heat, but the one with Nitrous Oxide results with less moles, it produces much more heat per amount of matter (2.25 times more heat energy per mole of reaction products). Also, Nitrogen has lower heat capacity than pollutant, which results in even higher temperature.

This reaction is inconsistent with volatiles being simple hydrocarbons (too much CO2 is produced), but it may be consistent with more complex organic molecules. If either volatiles or oxidizer is below 0.3mmoles, it reacts completely without any residue. The reaction rate by default (for example: in atmosphere) depends on temperature as clamp01(1 / (0.002 * (TC + 273.0)1.6 + 0.05) / 5 for oxygen as an oxidizer, and clamp01(1 / (0.0025 * (TC + 273.0)1.01 + 0.05) / 5 for nitrous oxide. Thus, the maximum default reaction rate is 0.2 and is valid at temperatures below 211C when without nitrous oxide and 107C when enough nitrous oxide is present (>~5%). After that reaction rate decreases logarithmically. At temperatures above 460C, nitrous enriched fuel combusts faster (at approx. 2x rate) than oxygen only. At higher temperatures, the difference is even greater, thus making the reaction more efficient and violent. Some devices (like [[H2_Combustor|H2 Combustor]] or [[Kit_(Gas_Fuel_Generator)|Gas Fuel Generator]]) increases rate of reaction (to 0.9 i.e. 90% in both cases).

If a combusting gas mix contains Volatiles, NOS, and O2, they all will react proportionally at same rate, according to aforementioned reactions (i.e. at 90% reaction rate and ideally balanced mix, each component will decrease by 90% from it's original amount). When mix is unbalanced and have either excess of volatiles or oxidizers, then proportions decrease accordingly, i.e. with excess of volatiles, only the amount of volatiles corresponding to amount of oxidizers (2 per Oxygen, 1 per Nitrous Oxide) will decrease proportionally; with excess of oxidizers, similarly, only the amount of oxidizers corresponding to the amount of volatiles is decreased at reaction rate, i.e. oxygen reacts at half the rate of nitrous oxide.

Volatiles have a specific heat of 20.4 Joule / mol.

===Notes===
* The Specific heat of 20 Joule / mol is in-between the specific heat of Hydrogen and Methane.
* The actual Autoignition temperature of Chloromethane in Oxygen is 625 °C (1,157 °F; 898 K), the game grossly underestimated the iginition temperature by about 11 times.
* Seems that a concentration of Volatiles greater than 6% in an atmosphere it is lethal to plants, keep attention on that designing a greenhouse, because [[Kit (Advanced Composter)|Advanced Composter]] will release Volatiles during the process.
* Enthalpy of Hydrogen (H2) combustion is precisely 286 kJ/mol
* As far as rocketry is concerned, Volatiles have a mass of 62.5 mol/kg
* Given the above, Volatiles have a molar mass of 16, suggesting it really is methane (CH₄).

== Description == 
The pumped gas rocket engine uses a 2:1 mix of [[Volatiles]] to [[Oxygen]]. It has a maximum thrust of 16.2kN and contributes 500kg to the overall weight of the rocket. Despite its Stationpedia entry, this engine has a measured specific impulse of 2,860s with a perfect volatiles and oxygen fuel mix and 2,080s with a 1:1 volatiles and N₂O mix.
To travel to mars orbit it is recommended the rocket weigh less than 8000kg.

Nitrous Oxide

Geeb: Added mass for rocketry

}}
Nitrous oxide "N2O" is an inert gas. Inhalation of nitrous oxide [[Cognition|stuns]] the player and eventually causes them to blackout.

Nitrous oxide has a specific heat of 23 Joule / mol.

Combusts with Volatiles at a 1:1 ratio (auto combusts at 50C), burns much hotter than h2/o2 (2:1 ratio).

For rocketry, N₂O has a mass of about 21.7 mol/kg, giving the 1:1 fuel mix a mass of 32.2 mol/kg compared to 62.5 for Vol/Oxy fuel mix.

Nitrous oxide is pretty easy to condense with a little pressure. Almost every N2O storage build will include a [[Phase Change guide#Heating_.2F_Cooling_with_phase_change_loops|condensation trap]] to avoid pipe ruptures.

Nitrous oxide naturally occurs as a small part of [[Ice (Nitrice)]], [[Ore_(Lead)]], and [[Ore_(Silver)]] or can be created by the [[Nitrolyzer]] from its constituent elements.

[[Alien Mushroom]]s breathe Nitrous Oxide and exhale oxygen and nitrogen.

* Added Nitrous Oxide. Currently inert, other than at certain concentrations will cause the player to take (progressively more) [[Cognition|stun damage]]. Only the first pass, will be utilized more with the implementation of surgery later.

Oxygen

Geeb: Added mass for rocketry

{{Fluidbox

}}

== Description == 
<blockquote><q>Oxygen provides energy when released in combustion, and also bonds with hydrogen to create [[Water]]. It is created by [[plants]], as well as from processing [[Ice (Oxite)]]. It is highly flammable at low temperatures.</q> 
'''- Stationpedia'''</blockquote>

[[Oxygen]], also known as '''O2''', 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.

Oxygen has an isochoric molar heat capacity of 21.1 J/mol⋅K.

Pure oxygen auto-ignites at 300°C when in [[atmosphere]] at any pressure when [[Volatiles|volatile]] gas is present.

'''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.

== Usage == 
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.

== Sources ==
You can collect Oxygen from the following sources:
