Explanation Solid changes into gas phase without passing through the intermediate liquid state are referred to as sublimation and the substance absorbs energy from the surrounding environment hence there is no time for melt. Carbon dioxide has solid, liquid and gas phases. Dry ice is referred to as the solid form of carbon dioxide and the sublimation temperature of dry ice is − 78 0 C ( 195.15 K ) under atmospheric pressure, not at 298 K . Liquid carbon dioxide is existing at a pressure above 5.1 a t m and under 31.1 0 C ( 304.25 K ) and above − 56.6 0 C ( 216.55 K ) which is the temperature of the triple point
