Dry ice, sometimes referred to as "Cardice" or as "card ice" is the solid form of carbon dioxide. It is commonly used as a
versatile cooling agent.
Dry ice is the solid form of carbon dioxide (chemical formula: CO2), comprising two oxygen atoms bonded to a single
carbon atom. It is colourless, odourless, non-flammable, and slightly acidic.
CO2 changes from a solid to a gas at −78.5 °C (−109.3 °F) with no intervening liquid form, through a process called
sublimation. The opposite process is called deposition, where dry ice changes from the gas to solid phase.
The density of dry ice varies, but usually ranges between about 1.4 and 1.6 g/cm3 (87–100 lb/ft3). The low temperature
and direct sublimation to a gas makes dry ice an effective coolant, since it is colder than water or ice and leaves no
moisture as it changes state. Its enthalpy of sublimation (Δ rH) is 393.5kJ/mol.
Dry ice is non-polar, with a dipole moment of zero, so attractive intermolecular van der Waals forces operate. The
composition results in low thermal and electrical conduction.
