    dry iceSolidified carbon dioxide that, at -78.5C and ambient pressure, changes directly to a gas as it absorbs heat. It is used as a coolant to induce the ice phase for supercooled cloud and fog modification procedures.



    carbon dioxideColorless gas, formula CO2, molecular weight 44; the fourth most abundant gas in dry air. The end product of the combustion or oxidation of organic material, including fossil fuels, CO2 is a very strong greenhouse gas and has very important radiative effects. Carbon dioxide is soluble in water, and the atmospheric concentration is buffered by dissolution in seawater. Carbon dioxide is taken up by the biosphere during photosynthesis, and large amounts of carbon can be stored in decaying organic matter.

    CO2 - , Google :
    "In liquid form carbon dioxide is used in fire extinguishers for electrical and similar fires as it does not conduct electricity. However it is not a good idea to use it on computer equipment as it can scramble magnetic information (due to the temporary dipole) - that's why they used to use Halon in computing centres."
