Answer 2

Answer:

Refrigerant

Explanation:

Dry ice is solidified carbon dioxide. When dry ice melts, it turns into carbon dioxide gas. Carbon dioxide gas is always present in the environment, but in low concentrations. It is colorless and odorless.

The quantity of dry ice used in a regular freezer or refrigerator is unlikely to produce carbon dioxide gas in sufficient quantity to cause a health problem. Dry ice can readily be used to keep foods cool in those types of containers.
