Dry ice vapor is carbon dioxide. The only argument that might be made is that the vapor, which is very cold, is more dense because of its lower temperature than "regular" or room temperature carbon dioxide.
Carbon dioxide is a colorless and odorless gas, by the way. What you actually see when dry ice, the solid form of carbon dioxide changes state from a solid to a gas (which is called sublimation) is water vapor in the air condensing into tiny droplets because of the intense cold near the dry ice.

∙ 13y agodry ice has no set temperature in solid phase but its sublimation temperature is around -80 degree Celcius. Liquid nitrogen while in liquid phase has to be at least -210 degree Celcius. Liquid nitrogen can snap freeze anything while it takes dry ice a few minutes.
Credential: I'm a scientist working with both these reagents on a regular basis in a research lab.

∙ 15y agoDry ice is solid, gaseous is a gas. Dry ice sublimes directly from a solid state to carbon dioxide gas when it is allowed to warm.

∙ 14y agoDry ice is typically colder than regular ice. Of course, regular ice submerged in liquid nitrogen would become colder than typical dry ice.

Wiki User
∙ 12y agoYes, when you freeze CO2 you get dry ice. It's called dry ice because on heating the dry ice it sublimes directly to the gaseous state without passing through the liquid phase.

Which ice melts faster dry ice or regular ice?
Dry Ice because dry ice is frozen carbon dioxide, totally different from ordinary ice, which is frozen water. Dry ice is much colder than water ice, thus it melts faster. P.S. DO NOT TOUCH IT FREEZES YOUR SKIN INSTANTLY!!
Can you mix dry ice with regular ice?
You can, the dry ice(solid form of carbon dioxide) will ultimately evaporate into carbon dioxide gas, and will then leave only the regular ice (frozen water). Because the dry ice will no longer exist, the regular ice will melt.
Will dry ice melt on contact with salt?
No, dry ice will not melt on contact with salt. In the first place, dry ice does not melt. It does not have a liquid phase under normal atmospheric pressure. It transforms from solid to gas, which is called sublimation. Dry ice sublimes, rather than melts. Secondly, salt has no effect on the sublimation of dry ice. Salt has an effect on frozen water, but it does not have an effect on frozen carbon dioxide. Salt is soluble in water, it is not soluble in carbon dioxide.
What do you think might be the reason that wet ice and salt are less active than dry ice?
What are you asking here? Dry ice sublimes into gaseous CO2, whereas salt is easily held by the water molecules in solution.
Does cyclohexane freeze in dry ice?
Cyclohexane's melting point is about +6 degrees Celsius. Dry ice (solid carbon dioxide) maintains a temperature of -78C in normal conditions. Cyclohexane will thus freeze on dry ice. In fact, a closed container of cyclohexane would freeze on regular, water ice. Regular hexane (linear) has a freezing point around -100C, and will remain a liquid on dry ice, much as ethanol or acetone do.

How do you use dry ice camping?
Since dry ice, which is frozen carbon dioxide, is even colder than regular ice (frozen water) it can be used to keep food cold for longer than regular ice does, when you take food with you in a cooler, on your camping trip.
Why does dry ice last longer when salt is sprinkled on it?
it is a process called freezing point depression. The salt lowers the freezing point of water therefore it has to be colder for the water to return to ice
Why would a ice cream man use dry ice then regular ice to keep his ice cream cold?
This is because, ice cream vendors add a very little amount of salt in the icecream or store them in boxes called ice boxes. This prevents melting and it allows the ice cream to be stable for a long time. Thank you Bloom
What does adding salt do to making homemade ice cream?
Add salt to the ice to make it colder.
Does dry ice make water colder?
Yes, it will make water colder.
Why does dry ice evaporate faster than a regular ice cube?
Dry ice is frozen carbon dioxide, totally different from ordinary ice, which is frozen water. Dry ice is much colder than water ice, thus evaporates quicker at room temperature. DO NOT TOUCH DRY ICE! It can hurt you badly.
Why is salt added to ice?
To make it colder, faster.
Is salt water colder then ice?
well for something to freeze it has to be 0 degrees or lower which is what ice is, frozen water. so the water has to be 1 degree or more to NOT freeze so the ice is colder than salt watercoz salt water is not frozen... does t6hat make sense? Actually, salt water CAN be colder than ice because the salt lowers the freezing point of the water.
What is colder than snow?
lots of things.. dry ice is colder i think and some chemicals go down to reealllyy low
What is the advantage of using dry ice in making ice-cream?
It is much colder.
Is dry ice cooler then an ice cube?
Yes it is a whole lot colder.
