If co2 can be liquefied can it be solidified and used for something else?

Answer 1

yup. dry ice.

Answer 2

Yes, but only under very, very cold temperatures.

It's called "Dry Ice," and one of its properties is that it sublimates, goes directly from the solid to the gaseous state.

It's primarily used for entertainment. You can put it in drinks and the smoke. (Airlines used to provide this during the 1970's. Seriously.) You can put it in a liquid and after it dissolves/melts, the liquid is carbonated, so you can make your own soft drinks.

It's used sometimes to pack and ship ice cream, because it's colder than water ice, and won't turn into a liquid and damage cardboard containers.

I also heard of someone fixing a minor dent in their car. Again, this was back in the 1970's. He went into Baskin and Robbins and got a piece of dry ice and applied it to the fresh dent. The extreme cold caused the metal to shrink and pop out the dent.

Dry ice has to be handled very carefully. You can't touch it, because you instantly get freezer burn on your skin. The liability is probably why no one uses it in the manners that I've described anymore.

Answer 3

CO2 when solidified is called dry ice--- check
Dry ice is made by solidification of CO2(gas) and turning it into CO2(solid) without passing through it's liquid form using pressure- the process is called sublimation. when it turns to gas again it doesn't pass to it's liquid form and is called disintegration..

Dry ice is use as

a propellant for co2 air riffles
gas in your fizzy drinks
smoke/mist effects on a stage play
etc

Answer 4

Most substances can exist in the three states: solid, liquid and gaseous. Just depends on the temperature and pressure.

In a solid state CO2 can be also be used as a cleaner (although I am not about to wash my clothes in it!) and as a fuel type used on space craft. I would imagine that it is mostly known as being used as dry ice though.

Answer 5

Under normal atmospheric pressure (1 atm) at −78.5 °C, carbon dioxide changes directly from a solid phase to a gaseous phase through sublimation or gaseous to solid through deposition. The solid form is typically called "dry ice". Liquid carbon dioxide forms only at pressures above 5.1 atm.
Dry ice has many applications:

Transporting items that need to remain cold or frozen, such as food, without needing any cooling source
Blast cleaning
Freezing warts to make removal easier
Keeping broken or powerless refrigerators and freezers cold
Loosening floor tiles by shrinking and cracking them
Carbonating water and other liquids
Repelling mosquitoes and other insects
Creating low-sinking dense clouds of fog for dramatic effects by putting it in water and therefore accelerating sublimation
Freezing water in pipes with no valves that are leaking or being repaired
Making ice cream[6]
Minor dent repairs - dry ice can force a car's sheet metal to contract, thus popping out a dent.

One of the largest alternative uses of dry ice around the world is dry ice blast cleaning. Dry ice pellets are shot out of a jet nozzle with compressed air. This can remove residues from industrial equipment, for example ink, glue, oil, paint, mold and rubber, replacing sandblasting, steam blasting, water blasting or other (potentially environmentally damaging) solvent blasting

Answer 6

of course solid co2 is used as dry ice to keep a freezing temp in many places.......

also the smoke u see in concerts and disco's are produced by solid co2......

Answer 7

Kinda dry subject Babe

cool it

Answer 8

you know those refrigerated trucks they call "reefers", that deliver refrigerated products all over the U.S. of A. and around the world? frozen CO2!

Dry ice but thats all.
