Sublimation
A gas can't turn directly into a solid but a solid can turn into gas for example ice to water vapor.
It is called sublimation when you turn a solid into a gas. When you turn a gas into a solid it is called deposition.
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
Both! The physical state of a substance can go straight from gas to solid, or can heat from solid to liquid and then to gas. The process a solid undertakes when it goes straight to its gas state from a solid state without first turning liquid is called sublimation.
To turn a liquid into a solid you have to freeze it. To turn a gas into a solid you must first turn it into a liquid, then freeze it.
Deposition when passing from gas to solid, sublimes when in the opposite direction.
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.
