The lowest temperature in the freezer is-18℃, while the preservation of dry ice needs -78.5℃. If you put dry ice in the refrigerator, it will melt, and it can volatilize about 2 to 3 kilograms 24 hours a day.
Dry ice is solid carbon dioxide, which is condensed into colorless liquid under the pressure of 6250.5498 kPa, and then rapidly solidified under low pressure.
