Sublimation
The most common example of a sublimable solid is Iodine.
Sublimation is a change of a substance from solid to gas without becoming liquid.
A solid that turns directly into a gas is dry ice. Sublimation
Solid turns directly into gas through the process of sublimation. This occurs when the solid is heated and skips the liquid phase to directly become a gas. An example of this is dry ice (solid carbon dioxide) turning into carbon dioxide gas without melting.
The gas can't generally turn straight into a solid, it has to change into a liquid and then a solid. When a gas turns into a liquid, the particles go closer together into groups and condensate. When the liquid turns into a solid, the particles all compress into a small space thus making a solid object.-----------------------------------------------------------------------But the phenomenon of change from a gas to a solid is also very known and is called deposition.
because it turns straight from a solid to gas and bypasses the liquid state.
Evaporation (or sublimation IF it goes straight from solid to gas).
some solids turn straight into a gas when heated. This process is called sublimation. A good example is solid carbon dioxide, also called dry ice. At atmospheric pressure, it turns straight into gaseous carbon dioxide
When a substance goes from a gas to a solid it is called deposition.
