It is the solid form of carbon dioxide. It does not melt like normal ice. The dry ice sublimates, leaving behind no residue like the regular ice. It is not wet like the normal ice and has longer shelf-life. Its constituents are Carbon and Oxygen while the other has hydrogen and oxygen.

Dry ice is CO2(solid),regular ice cube is H2O(solid).

Dry Ice is frozen carbon dioxide, a normal part of our earth's atmosphere. It is the gas that we exhale during breathing and the gas that plants use in photosynthesis. It is also the same gas commonly added to water to make soda water. Dry Ice is particularly useful for freezing, and keeping things frozen because of its very cold temperature: -109.3F or -78.5C. Dry Ice is widely used because it is simple to freeze and easy to handle using insulated gloves. Dry Ice changes directly from a solid to a gas -sublimation- in normal atmospheric conditions without going through a wet liquid stage. Therefore it gets the name "dry ice."

As a general rule, Dry Ice will sublimate at a rate of five to ten pounds every 24 hours in a typical ice chest. This sublimation continues from the time of purchase; therefore, pick up Dry Ice as close to the time needed as possible. Bring an ice chest or some other insulated container to hold the Dry Ice and slow the sublimation rate. Dry Ice sublimates fast ...more

Dry ice is solidified carbon dioxide. The difference - water ice melts into liquid while dry ice sublimates directly from solid to gas.

Both dry ice and ice have cold temperatures and are commonly used for freezing and cooling. Ice forms at 32F while dry ice forms at minus 109.3F. Water ice is created when water is exposed to very low temperatures while dry ice is frozen carbon dioxide. Their main difference however lies in the fact that regular water ice melts into liquid while dry ice sublimates directly from solid to gas.

Dry ice is made when carbon dioxide (CO2) gas is compressed in a high-pressure container until it liquefies. Upon the release of pressure, some of the liquid turns into gas that cools some of the liquid into its solid state in the form of dry ice.
