Can dry ice be placed in the refrigerator?

In modern life, people can make all kinds of complicated things. For example, dry ice is a very commonly used substance. It is solid carbon dioxide that slowly releases white smoke. It can be used in various celebrations to create a beautiful atmosphere. The volatile nature of dry ice makes it very difficult to preserve. Therefore, people are quite concerned about the preservation of dry ice. Let's take a look at whether dry ice can be placed in the refrigerator.

Dry ice itself is not ice. It is a solid object formed by rapid condensation of carbon dioxide after being pressurized (about 6200 kPa). The evaporation temperature of dry ice is -78 degrees. That is to say, as long as the temperature is higher than this, dry ice will directly sublime into gas.

Reasons why dry ice cannot be placed in the refrigerator:

The vaporization point of dry ice is minus 78.5 degrees Celsius and it sublimates very easily. The lowest temperature in the refrigerator freezer is -18 degrees Celsius, and dry ice can easily sublime in the refrigerator freezer.

When dry ice sublimates into carbon dioxide, it releases gas that is 1,000 times larger than the original solid dry ice. If it is placed in a certain closed environment, the gas produced by sublimation will exert great pressure on the inner wall of the sealed container. If it is placed in a refrigerator, the refrigerator door will expand open. In serious cases, the inner wall of the refrigerator will be squeezed and deformed or the sealed container will explode.

Dry ice: Dry ice is solid carbon dioxide, which is obtained by condensing carbon dioxide into a colorless liquid at a pressure of 6250.5498 kPa and then rapidly evaporating it under low pressure. Carbon dioxide is a colorless and odorless gas under normal conditions. It exists naturally in the air. Although the content of carbon dioxide in the air is relatively small (about 0.03% by volume), it is one of the most important gases we know of. Dry ice is extremely volatile and sublimates into non-toxic, odorless gas carbon dioxide, which is 600-800 times larger in volume than its solid state. Therefore, dry ice cannot be stored in completely sealed containers, such as plastic bottles. Mixing dry ice with liquids can easily cause explosions.
