Detailed explanation-1: –The process in which a solid directly gets converted directly to a gaseous state is called sublimation. So, here solid state does not get converted to liquid state in the process of attaining gaseous form.
Detailed explanation-2: -sublimation, in physics, conversion of a substance from the solid to the gaseous state without its becoming liquid. An example is the vaporization of frozen carbon dioxide (dry ice) at ordinary atmospheric pressure and temperature. The phenomenon is the result of vapour pressure and temperature relationships.
Detailed explanation-3: -Sublimation is the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage. For those of us interested in the water cycle, sublimation is most often used to describe the process of snow and ice changing into water vapor (gas) in the air without first melting into water.
Detailed explanation-4: -Sublimation is the process by which solid converts directly to liquid state.
Detailed explanation-5: -When heated, solid iodine sublimes i.e. it directly changes into a gaseous state without converting to liquid state.
