Question

how can you appreciate the fact that dry ice is used to freeze perishable foods .​

Answer 1

Here is your answer

Dry ice is the solid form of carbon dioxide , the molecule that animals breathe out when we exhale and plants take in when they do photosynthesis. Carbon dioxide is a gas at room temperature, and it freezes solid at a much lower point than water: -109 degrees Fahrenheit (-78 C).

Freezing carbon dioxide is also more complicated than freezing water. To make dry ice, carbon dioxide gas is first cooled and pressurized to turn it into a liquid, according to Continental Carbonic Products, Inc, a dry ice manufacturer. The liquid is then depressurized and allowed to expand back into a gas. This expansion causes a rapid temperature drop, and some of the carbon dioxide freezes into solid pellets of dry ice. Those pellets are then shaped into chunks which can be used in food storage facilities, biomedical labs.
