What is dry ice?

Dry ice is solid carbon dioxide (CO2) that sublimates under normal pressure at −78.48 ° C, i.e. passes directly into the gas phase without melting beforehand. Dry ice does not occur naturally on Earth, but in the CO2-rich atmosphere of Mars it freezes in winter at higher latitudes and forms the well-known polar caps. Some meteoroids also contain large amounts of it.
