Gas may refer to:

• Atmosphere
• Carbon Dioxide (CO₂)
• Fuel (66.6% H₂ + 33.3% O₂)
• Hydrogen (H₂)
• Nitrogen (N₂)
• Nitrous Oxide (N₂O)
• Oxygen (O₂)
• Pollutants (X)
• Volatiles
• Water (H₂O)

Gases

Name	Filter Color	Molar Heat Capacity
Carbon Dioxide (CO2)	Gray	28.2
Nitrogen (N2)	Green	20.6
Nitrous Oxide (N2O)	Green	23.0
Oxygen (O2)	White	21.1
Pollutant (X)	Black	24.8
Volatiles (H2)	Red	20.4

^{* Water is now a liquid.}

Mixtures

Name	Contents	Tank Color	Notes
Fuel	67% H2, 33%O2	Orange	Autoignition at 50C
Air	75% N2, 25% O2	White	20kPa O2 is required for human player breathing. Hyperoxia is not simulated.

Simulation Mechanics

• Partial ideal gas law (PV=nRT) is simulated.
• Fluid dynamics, thermal conductivity, phase change, the rest of the ideal gas law, and others are not simulated.
• Thermal radiation is not simulated, but vacuum atmosphere (not rooms) will absorb a fixed amount of energy per tick. The sun adds a fixed energy per tick.
• Each environment grid cube acts as a single point and each connected pipe network acts as a single point.
• Insulation is perfect/infinite.
• All pumps/mixer also act as a check valve.
• Gas stoichiometry is not utilized. (i.e. Igniting 2H₂ + O₂ does not yield 2H₂O)
