Dry ice is frozen carbon dioxide, created by compressing carbon dioxide gas. The carbon dioxide needs to be frozen at -109.3F or -78.5C. When the carbon dioxide compresses some of the liquid turns into gas making the fog around dry ice. The fog freezes some of the liquid to turn them into blocks that create the ice shape. Reason why when it melts it turns into a gas not liquid.

Some of the ways dry ice is an alternative way to keep frozen food cool. If you’re freezer is broken, dry ice can be used to keep them cool since it gives off cooling gas. Dry ice can also be used to make dents damage to be fixed as it makes the metal condense. As the dry ice condenses the metal it makes it shrink to pop out the dent. This is useful toward car damage
