Sublimation of dry ice. A fog-like vapour spills out of a glass beaker containing dry ice. Sublimation is the conversion of a solid directly to a vapour state by heating. Dry ice is solid carbon dioxide. Carbon dioxide is a colourless gas at room temperature but becomes a liquid under compression; if the liquid is allowed to expand rapidly to atmospheric pressure,it cools suddenly and freezes to dry ice. Dry ice sublimes (turns straight into a gas from the solid state) at -78.5 degrees Celsius (195 degrees Kelvin). If mixed with water it sublimes,as seen here,producing thick clouds of fog | |
