Subliming dry ice pellet, with white frost on the surface. Dry ice colloquially means the solid form of carbon dioxide.It is commonly used for temporary refrigeration as CO 2 does not have a liquid state at normal atmospheric pressure and sublimes directly from the solid state to the gas state.

Both flasks are submerged in a dry ice/acetone cooling bath (−78 °C) the temperature of which is being monitored by a thermocouple (the wire on the left). A cooling bath or ice bath , in laboratory chemistry practice, is a liquid mixture which is used to maintain low temperatures, typically between 13 °C and −196 °C.

Ice became a mass-market commodity by the early 1830s with the price of ice dropping from six cents per pound to a half of a cent per pound. In New York City, ice consumption increased from 12,000 tons in 1843 to 100,000 tons in 1856. Boston's consumption leapt from 6,000 tons to 85,000 tons during that same period.
The Santa Fe Refrigerator Despatch (SFRD) briefly experimented with dry ice as a cooling agent in 1931. The compound was readily available and seemed like an ideal replacement for frozen water. Dry ice melts at −109 °F or −78.33 °C (versus 32 °F or 0 °C for conventional ice) and was twice as effective thermodynamically.
