Carbon dioxide does not boil, at least not under conditions common on earth. It changes from solid directly to gas form, a process known as “sublimination.”

Watch what happens to a piece of dry ice on a tabletop and you’ll see that this poster is indeed very correct.
Boiling point -78.6c
You are referring the phase transition of C02. You are correct that it lacks a liquid phase and sublimates directly to a gas. However, that sublimation only occurs at the boiling point of C02. Which is at a temperature above -78.5 degrees Celsius.
