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==
* Ideal gas law (PV=nRT) is simulated.
* Thermal conductivity is not simulated. (f.e. heat is transferred at the same fixed rate for all substances; structures and devices are ignored)
* Thermal radiation is simulated. (caveat: radiated infrared is not absorbed by nearby objects)
* Phase change is simulated. (caveat: simplified and with fixed temperature for solid state)
* Fluid dynamics are not simulated. (caveat: thermal convection is partially simulated)
* Each environment grid cube acts as a single point and each connected pipe network acts as a single point.
* All pumps/mixer also act as a check valve.
* Gas stoichiometry is partially utilized. Some reactions do not reflect real-life.
* Gas pressure determines liquid pressure; gravity/height is ignored.
* Pipes have arbitrary stress value determined by amount of non-correct phase of substance within them (liquid in a gas pipe).
* [bug?] Liquid temperature is controlled by gas temperature. (if no gas present, liquid heater will not function)
