Here is some interesting information on Co2.
Phase Diagram of Carbon Dioxide
The phase diagram of CO2 has some common features with that of water: sublimation curve, vaporization curve, triple point, critical temperature and pressure. Of course, the P and T values of are unique to carbon dioxide. The phase diagrams of water and carbon dioxide are compared here.
The triple point of carbon dioxide occure at a pressure of 5.2 atm (3952 torr) and 216.6 K (-56.4oC). At temperature of 197.5 K (-78.5oC), the vapor pressure of solid carbon dioxide is 1 atm (760 torr). At this pressure, the liquid phase is not stable, the solid simply sublimates. Thus solid carbon dioxide is called dry ice, because it does not go through a liquid state in its phase transition at room pressure.
The critical temperature for carbon dioxide is 31.1°C, and the critical pressure is 73 atm. Above the critical temeprature, the fluid is called super-critical fluid.
To be more precise, the various point of the phase diagram are further descibed below. In the phase diagram of (a) H2O and (b) CO2, the axes are not drawn to scale. In (a), for water, note the triple point A (0.0098°C, 4.58 torr), the normal melting (or freezing) point B (0°C, 1 atm), the normal boiling point C (100°C, 1 atm), and the critical point D (374.4°C, 217.7 atm). In (b), for carbon dioxide, note the triple point X(-56.4°C, 5.11 atm), the normal sublimation point Y(-78.5°C, 1 atm), and the critical point Z (31.1°C, 73.0 atm).

I guess creating liquid carbon dioxide is out of the question for me right now hehe.
Does anyone know what exactly Flourish Excel is and why/how it creates CO2?
