Dry Ice

Definition - What does Dry Ice mean?

Dry ice is the solid form of carbon dioxide. The main use of dry ice is as a cooling agent. As a result of its very cold temperature, dry ice is a very useful freezing agent. Dry ice derives its name from the fact that it passes from a solid to a gaseous state in normal atmospheric conditions without going through a wet liquid stage.

Safeopedia explains Dry Ice

Dry ice sublimates, changes from a solid to a gas, at a rate of five to ten pounds every twenty four hours. This is a faster rate than regular ice. However, dry ice will extend the life of regular ice. Dry ice provides more than twice the cooling energy per pound of weight and three times the cooling energy per pound of volume of regular water ice.
