Description

You breath it out, plants breath it in. They don't grow without it. You can use items placed in Gas Filter slots to remove this from the atmosphere. Carbon Dioxide has a moderately high specific heat, meaning it makes a good coolant for devices like the Wall Cooler. Water is better, but usually has more important uses.

Carbon Dioxide, or CO2, is a non-flammable gas found in some atmospheres naturally (such as Mars). It can also be produced by burning Fuel or Coal, smelting most ores (e.g. Iron, Copper, and Silicon) and through human respiration.

Details

Carbon Dioxide will condense into Liquid Carbon Dioxide starting at 265.05 K (-8.1 °C). With such a low temperature requirement, most setups will store Carbon Dioxide as a gas and use Liquid Carbon Dioxide as a coolant.

Carbon Dioxide is required for most plants to grow. Plants will inhale the Carbon Dioxide to create Oxygen which can be harvested using vents. Stationeers should monitor their plants to ensure they always have enough Carbon Dioxide as, given enough time, they can convert all of it into Oxygen.

Carbon Dioxide has an isochoric molar heat capacity of 28.2 J/mol⋅K, making it a superior coolant to Pollutant. Both are greatly surpassed by water, though water is harder to find and has more important uses.

Sources

You can collect Carbon Dioxide from the following sources:

Coal Ore 10 mol
Charcoal 3 mol
Copper Ore 1 mol
Gold Ore 0.2 mol
Iron Ore 0.5 mol
