Dry ice

Dry ice is a genericized trademark for solid ('frozen') carbon dioxide. The term was coined in 1925.

Dry ice at normal pressures does not melt into liquid carbon dioxide but rather sublimates directly into carbon dioxide gas at −78.5?C (−109.3?F). Hence it is called "dry ice" as opposed to normal "wet" ice (frozen water).

Dry ice is produced by compressing carbon dioxide gas to a liquid form, removing the heat produced by the compression (see Charles' law), and then letting the liquid carbon dioxide expand quickly. This expansion causes a drop in temperature so that some of the CO2 freezes into "snow" which is then compressed into pellets or blocks.
