[Idea] Realistic boiling points

[djdookie]

What do you think about including this into the base game? Lots of fun or too complex to handle?

I`d say it`s not possible without a proper pressure system. Like we can change phase transition points based on mass but even at the start of the game the amount of oxygen consumed and CO2 produced by dupes just doesn`t add up. It causes the pressure to fall low early and with such a system it could cause water to boil early on.

It gets worse later when we consider electrolizers. The pressure of the gasses they produce should be based on the molar amounts rather than their mass. This emans that rather than having 1 tile of hydrogen per 8 tiles of oxygen we should get 2 tiles of dydrogen per 1 tile of oxygen. Pumps wouldhave to be changed as well. That`s a lot of changes and not a simple task by any means.

I mean yes it`s possible but requires rebuilding the game from the base up. I don`t think it will happen anythime soon.

Aren't electrolizers actually following the atomic masses of hydrogen and oxygen in water already?  The chemical formula is H2O.  2 hydrogen atoms is 2.01568 U, 1 oxygen atom is 15.999 U, combined is 18.01468 U.  That means that the mass of water is 11.189% hydrogen and 88.811% oxygen.  That's the same as the electrolizer's current output.

This is right but it only means the masses produced are proper. The gas pressure depends on a different equation: pV = nRT (notice there is no mass in the equation). This means pressure of a gas doesn`t depend on the mass but on the amount of atoms (n). Assuming we got hydrogen and oxygen in the same room in hte same temperature(T) so that pressure of both gasses(p) is the same then hydrogen should take the space(V) based on the amount of atoms(n) so twice as much as oxygen when produced by an electrolizer. (R is a constant)

It goes further. Hydrogen would have the same pressure as oxygen at roughly 1/16 of the mass. This means vents would overpressurise at about 112.5g of hydrogen. Pumps would have to transfer the gas based on pressure as well meaning all of the calculations would have to be redone. Without a proper pressure system (with an overlay) it would be impossible to determine where the pressure of different gasses is safe and why water boils in one area and refuses in another.

I mean i`m all for realism but it`s not as simple as add 1 variable so phase changes depend on pressure. You need to build the entire pressure system first and that causes all sorts of trouble.
