Sublimation is a physical process in which a solid directly converts into a gaseous (vapor) state without going through a liquid state. The latent heat of sublimation at a particular temperature is the amount of heat required to convert a unit mass of solid into gas. For example, when ice sublimates into vapor, the amount of heat required at 0°C is estimated equal to 2,838 kJ/kg, which is the latent heat of sublimation of ice at 0°C. In the crystal growth of ice and snow in atmosphere, this process plays a dominant role. This process is opposite to the process of deposition.
