Dry ice is solid carbon dioxide. It is commonly used as a versatile cooling agent. Dry ice sublimes, changing directly to a gas at atmospheric pressure. Dry ice is commonly used to package items that need to remain cold or frozen, such as ice cream, without the use of mechanical cooling. In medicine it was used to freeze warts to make removal easier, although that application is now done with the use of liquid nitrogen. In the construction industry it is used to loosen floor tiles by shrinking and cracking them, as well as to freeze water in valveless pipes to allow repair. In laboratories, a slurry of dry ice in an organic solvent is a useful freezing mixture for cold chemical reactions.
