Part C
Open the phase diagram for CO₂ given in the introduction again. Use the phase diagram for CO₂ in the interactive activity and determine which of the following statements are correct.
Check all that apply.
All three phases of CO₂ exist simultaneously at the triple point.
When the pressure is 1 atm, there is no temperature at which the liquid phase of CO₂ exists.
CO₂ is a gas under normal conditions of temperature and pressure.
Movement across boundary line BO corresponds to a phase change.
CO₂ forms a supercritical fluid at temperatures less than 31°C.
When the pressure is 4 atm and the temperature is more than -5.6°C,CO₂ exists as a solid.
