Question

What is the another name of solid CO²? How it is prepared?

Answer 1

Hi
__________
It's also known as cardice.
3 ways to make it:-
1It is manufactured by compressing and cooling gaseous CO2 under high pressure to initially produce liquid CO2.
2The liquid is then allowed to expand under a reduced pressure to produce CO2 snow, and finally, this snow is compressed by a hydraulic press into convenient Dry Ice blocks, slices or pellets.
3The density of the compressed CO2 snow depends on the applied pressure and the pressure time. The density of the Dry Ice block can reach 1.56g/cm3 as a maximum at a temperature of -78.64°C.
