Carbon Dioxide
-
Reacts with water to create carbonated water.
the gas deposits directly to a solid at temperatures below ?78 °C (?108 °F; 195 K) and the solid sublimes directly to a gas above ?78 °C.
The solid would be Dry Ice.
Plant reacts to contact with CO2 to create O2 but only if the plant is also in contact with water.
Optionally you could have the LIFE and FIRE put off CO2 -
What does carbonated water do? o.o
Having an element with no liquid state would be pretty cool, but it'd be helpful if the element itself had some special chemical use. CO2 wouldn't be able to set fire, and we -do- have smoke (which could maybe be arranged to do this at near absolute zero temperatures without any issues O_O) -
Wait so I actually have a viable idea this time? That just made my day. (not that i think it will be integrated) Well Carbonated water would obviously put off CO2 and (optionally) over time return to regular water. But instead of appearing on the surface the CO2 would spawn mostly around the edges of the carbonated water (just like it does when you put it in a glass). But also all throughout it would spawn just not as much. Carbonated water would also put off CO2 at a higher rate if it's velocity is changed (such as sudden stop in motion or shaking). Another thing is that it would build up pressure when put in a closed container. However just as with real carbonated water if the pressure is too high it will still build pressure but the CO2 will not appear until pressure is released. Then it is released in a sudden burst that would cause the water to shoot out along with the CO2 (as pop often does). The build up would have a limit if stagnate and if agitated it's pressure limit would increase and over time decrease again as the carbon (which would be present but not appear due to pressure) would combine back with the water. (all of these things could be changed a bit i suppose, i'm just throwing it out there)
Now as for the CO2 itself...
•CO2 would be given off when any combustion takes place (in variable amounts)
•Dry Ice is always below ?78 °C at regular atmospheric pressure, regardless of the air temperature.
•This is a quote from Wikipedia about dry ice/CO2 (I am not good at chemistry): "At temperatures below ?56.4 °C
(?69.5 °F) and pressures below 5.13 atm (the triple point), CO2 changes from a solid to a gas with no intervening liquid form, through a process called sublimation. The opposite process is called deposition, where CO2 changes from the gas to solid phase (dry ice). At atmospheric pressure, sublimation/deposition occurs at ?78.5 °C (?109.3 °F)."
•The density of Dry Ice is about 1.4 g/cm3 (100 lb/ft3).
•Dry Ice does not conduct Electricity.
•Carbon dioxide extinguishes flames
... And thats all i've got, I'm not really good at Chemistry. If any of you Chemistry Junkies have more to add feel free to point out things i missed/got wrong. -
Actually we were seriously considering just adding the function to smoke, along with a new element for the solid state and (maybe) carbonated water. All of the stuff with pressure and bubbles, too. (since that's sort of the whole idea.)
The tricky part really is that it would mean extinguishing flames might be tricky since smoke would essentially be doubling the part of CO2. A color change for CO2 (that isn't spawned from fire) might occur too. Making bubbles stay at the edges of the container might be tricky but could maybe be done. The trick would be more preventing the bubbles from rising so quickly over the liquid that spawns them, since generally liquids have more density than gases and instantly rise. Then again still most of this is probably easy with just a few lines of code.
Fixing it so that the liquid doesn't immediately explode due to the slightest movement and yet, fizzles nicely when pressure changes abruptly is really the tricky part. -
Well I look forward to seeing if this actually makes it into the game :)
