* phase change has been added to the game system and most gasses now have an associated [Liquid] and a pure Solids phase .

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 compounds; 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)
