Question

explain formation of dry ice


see attachment​

Answer 1

Answer:

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.

Answer 2

Answer:

Dry ice is solid. It sublimates or changes states from a solid to a gas at temperatures of -78 degrees Celsius under normal atmospheric pressure of 1 atm. Because of its low temperature at normal atmospheric pressure, it is useful as a coolant. When dry ice is placed into warm water, a cloud forms.
