No, I would not call CO2 a sublime (unparalleled; supreme) substance, However, CO2 does sublimate (to change directly from a solid to a vapour or gas without first melting).

Is urea a sublime substance?
Urea is not a sublime substance.
Which substance will sublime at room temperature?
CO2(s) and I2(s) Carbon dioxide as a solid and iodine crystals as solids. These are the two most important sublimation compounds! When I say sublimation, you say CARBON DIOXIDE AND IODINE! :)
Why does say carbon dioxide sublime?
Only some substances sublime because of pressure. Some solids have a high enough vapor pressure and triple point that makes them sublime in the air, which may be easier than evaporating.
Will sugar sublime?
No. Sugar is a solid. When heated, it will burn, but not sublime. (To sublime is to go from the solid state to the gaseous state with no liquid state in between. The most common thing that will sublime is solid carbon dioxide, which we know as "dry ice". It's a solid below about -109F, and sublimes into the gaseous state above that. Carbon dioxide has no liquid state at atmospheric pressure; it is only liquid below 0 degrees F at pressures above 60PSI.)
What solid substance never melts?
solid carbon dioxide
How is Carbon Dioxide a substance?
Carbon dioxide is a pure substance that is a compound.
Is carbon dioxide a pure substance or a compound?
Carbon dioxide (CO2) is a compound and can be also a pure substance.
What are four things that can sublime?
Iodine, dry ice (solid carbon dioxide), naphthalene (mothballs), and camphor are examples of substances that can sublime. Sublimation is the process by which a substance transitions directly from a solid to a gas without passing through the liquid phase.
Is carbon dioxide a substance or a mixture?
It is A
Is carbon dioxide a mixed substance?
Carbon dioxide is a compound of two gases; Carbon and Oxygen. Therefore it is not a mixture, or mixed substance.
Is carbon dioxide a homogenous mixture?
No, carbon dioxide is not a mixture. It is a pure substance.
Is carbon dioxide a homogeneous heterogeneous?
Neither. Carbon dioxide is a pure substance, not a mixture.
Is carbon dioxide a heterogeneous or homogeneous?
Neither. Carbon dioxide is a pure substance, not a mixture.
What substance is carbon dioxide?
Co2
Is urea a sublime substance?
Urea is not a sublime substance.
Is carbon dioxide a heterogeneous mixture or homogeneous mixture?
Carbon Dioxide is not a mixture. It is a chemical compound composed of two oxygen atoms and one carbon atom.
Is carbon dioxide a substance or a mixture and what kind?
It's a substance
