==Gases==

Stationpedia has simple phase diagrams for all Gases, shown in composite below. A more complex phase change diagram can be located [https://www.desmos.com/calculator/voj4scjipd Here]

Phase changes have been added to the game system and most gases now have an associated [[:Category:Liquid|Liquid]] and a pure solid phase.

The following exist only in solid state and have no gaseous form: Charcoal, Coal, Silicon, Iron, Copper, Nickel, Silver, Gold, Lead, Uranium.

==Simulation Mechanics==

|-
! Concept
! Simulated
! Notes
|-
| Ideal Gas Law (PV=nRT)
| Partial
| Pressure will change with temperature, volume, and moles; Temperature will not change
|-
| Thermal Conductivity
| No
| Rate of energy transfer is the same for all substances
|-
| Thermal Radiation
| Partial
| Radiated heat is not absorbed by nearby objects
|-
| Phase Change
| Partial
| Gas/Liquid have simplified graph; Solid has a fixed temperature; Plasma is ignored
|-
| Fluid Dynamics
| No
| 'Convection' parts work in pressurized environment, other parts work in vacuum
|-
| Gas Stoichiometry
| No
| The various reactions are arbitrary and vary depending on device used for different products from the same reactants
|-
| Gravity/Density
| No
| Gas/Liquid is present in all directions
|-
| Environment Volume
| Yes
| Each environment cube acts as a single point with fixed volume
|-
| Pipe Volume
| Yes
| Each pipe network acts as a single point with fixed volume depending on number of pipes segments
|-
| Flow Direction
| Yes
| All pumps and mixer act as check valve, passive check valve available, other valves are not one-way
|-
| Pipe Integrity
| Yes
| Liquid pipes hold low pressure, but may contain both liquid and gas without consequence; Gas pipes hold high pressure, but stress and break with too much liquid
|-
| Heat Transfer
| Partial
| Liquid temperature is controlled by gas temperature (if no gas, liquid heater will not function)
