Phase changes have been added to the game system and most gases now have an associated 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.
Mixtures
| Name | Contents | Tank Color | Notes |
|---|---|---|---|
| Fuel | 67% H2, 33% O2 | Orange | Autoignition at 573.15 K / 300 °C |
| HydroNox | 50% H2, 50% N2O | N/A | Autoignition at 323.15 K / 50 °C |
| Air | 75% N2, 25% O2 | White | 16 kPa Partial Pressure O2 minimum is required for human player breathing. Hyperoxia is not simulated.(NOTE: Suit air mixture should be 100% O2) |
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) |
