Question

what happens to dry ice when pressure is realeased?what is it chemically called?give one application of dry ice.

Answer 1

Dry ice is in reality Carbon Dioxide, which has been converted into a solidified state by applying a great amount of pressure on it .

Therefore, when dry ice does not receive the pressure, or when the pressure is removed, then the state of dry ice changes to the state of gaseous carbon dioxide again.

Dry ice is a solid form of Carbon Dioxide ( CO2). It can be prepared from purest form of Corbon dioxide gas by pressurizing and refrigeriting it until conversation of gas form to liquid form i.e. liquid CO2. In next step when the pressure is reduced, the liquid carbon dioxide get vaporized and due to this the temperature is further reduced and liquid carbon dioxide started conversation into white sold form. This sold form of Carbon Dioxide is called DRY ICE. The temperature of dry ice remains approximately -78 degree C. ( Minus 78 Degree Celsius) Dry Ice Uses & Applications - Consumer
