Liquid CO2 rivers, lakes or oceans

  • #1
Lets say you have planet with 2 Earth radii and 8 Earth masses. The atmosphere is 50 bar and is made up of 85% nitrogen, 10% hydrogen 3% argon, 1% CO2 and 1% other gases. The planets average temperature is 280 K/44 F.

Since CO2 is a liquid at this pressure and temperature would it form rivers, lake or oceans of liquid CO2 mixed with liquid water or will it stay in a gaseous form because of its lower abundance of other gases and the overall density of the atmosphere?

At 50 bar and 1% of CO2 partial pressure of carbon dioxide is just 0.5 bar (0.5 atm).

OK, Borek. This means that the partial pressure of CO2 is too low, and no liquid CO2 exists.
Correct ?
