How is it that CO2 when stored in a cylinder as a liquid is at a lower pressure than CO2 as a gas?

Question

Even though thay are the same temperature. Shouldn't it be the other way around?

forget it, I found the answer. Its always a liquid when stored in a cylinder, the difference is whether you withdraw it in the liquid of gaseous phase.....

Answer 1

CO2 at atmospheric pressure is a gas.

To store it at high pressure as a gas it has to be compressed.

As a liquid, it can be held as liquid at atmospheric pressure for a short time.

To keep in a cylinder as a liquid, it has to be maintained at or above its critical pressure in relation to its temperature.

Answer 2

Those gas pressure equations stop working as soon as there's a state change.
