Guide to Gases ErisEN
Gases of Atmos
There are 5 major gases in the gas pipes of the CEV Eris. They are (in no particular order) Oxygen, Carbon Dioxide, Nitrogen, Nitrous Oxide and Plasma. For most of the ship outside engineering it should be only the first 3 on the list. Standard atmosphere is about 78% Nitrogen with 21% Oxygen with a little bit of Carbon Dioxide due to respiration.
Gas Quick Reference
| Gas | Storage Canister | Specific Heat [J/(mol*K)] | Molar Mass [kg/mol] | Notes |
|---|---|---|---|---|
| Oxygen |  |
20 | 0.032 | Oxidizer, necessary for human life |
| Nitrogen |  |
20 | 0.028 | - |
| Carbon Dioxide |  |
30 | 0.044 | Byproduct of respiration and combustion |
| Nitrous Oxide |  |
40 | 0.044 | Provides a long duration anesthetic, knocks out most biological entities |
| Plasma |  |
200 | 0.405 | Toxic to most biological life, flammable |
Oxygen (O2)
Oxygen is necessary for life as we know it.
Nitrogen (N2)
Nitrogen is a common gas that actually makes up the bulk of breathable atmosphere on the CEV Eris.
Carbon Dioxide (CO2)
Carbon Dioxide is the natural output of most forms of oxidization.
Nitrous Oxide (N2O)
Nitrous Oxide (aka laughing gas) is a useful tool for putting targets to sleep without killing them.
Plasma (!!!)
Plasma is a blessing and a curse.
Dealing with Gases
Scrubbers and Vents
The first line of defense against messes involving atmosphere are the ship's ventilation and filtering system.
Repairing Atmos Pipes
Often damage to the ship will also break the pipes that transport gases throughout the ship. These breaks can be repaired these steps:
- Numbered list item
Protective Equipment
Individuals can protect themselves against errant gases by wearing the appropriate protective equipment.
Field Work
In the case that everything has gone wrong, the crew can manually work to filter their local atmosphere.

|---|---|---|
| Portable Air Filter |  |
Filters gases out of the air into an air tank |
| Portable Air Pump |  |
Pumps atmosphere into a air tank |
