WebAug 10, 2024 · At room temperature and standard pressure, a piece of dry ice (solid CO 2) sublimes, appearing to gradually disappear without ever forming any liquid. Snow and ice sublime at temperatures below the melting point of water, a slow process that may be accelerated by winds and the reduced atmospheric pressures at high altitudes. WebFrom a gas, the CO2 needs to be converted into a liquid before it can become solid dry ice. In order to get the CO2 gas into a liquid, it is pressurized and refrigerated. Once it liquefies, the pressure is reduced causing some of the liquid CO2 to vaporize. As the CO2 vaporizes it causes a rapid decrease in temperature.
