Your answerChoose one option.

At 200 K, on increasing the pressure from 1 to 50 atm, CO₂ gas condenses to liquid.

It is not possible to obtain liquid CO₂ from gaseous CO₂ below 5.11 atm.

Both liquid and gas phase of CO₂ coexist at 298.15 K and 67 atm.

With increasing pressure, the melting point of solid CO₂ increases.
