Question

what does carbon dioxide need to change into dry ice​

Answer 1

Dry Ice is manufactured by compressing and cooling gaseous CO2 under high pressure to initially produce liquid CO2. The 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.
