WebEven ice has a measurable vapor pressure near its freezing point, as evidenced by the tendency of snow to evaporate in cold dry weather. There are other solids whose vapor pressure overtakes that of the liquid before melting can occur. Such substances sublime; a common example is solid carbon dioxide (dry ice) at 1 atm of atmospheric pressure.
