State change from solid directly to gas is called sublimation, for example, dry ice - CO2(s) sublimates into gas CO2(g).
Solidification
Some substances can go straight from solid to gas phase by a process called sublimation. A gas going to a solid is a process known as Deposition.
Not always. Some go straight from solid to gas eg dry ice ... called 'sublimation'.
Naphthalene and camphor the process is sublimation
Sublimation is a change of a substance from solid to gas without becoming liquid.
Evaporation (or sublimation IF it goes straight from solid to gas).
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.
No. They go straight from solid to gas.
yes. eg: naphthanol, iodine
Some substances can go straight from solid to gas phase by a process called sublimation. A gas going to a solid is a process known as Deposition.
Mercury
Deposition when passing from gas to solid, sublimes when in the opposite direction.
Not always. Some go straight from solid to gas eg dry ice ... called 'sublimation'.
sublimation!!
sublimation!!
No. Carbon is a solid at room temperature and will sublimate (go from solid straight to gas i.e. no liquid) at 3900 Kelvin.
liquids don't sublimate, the definition of sublimation is a solid that changes directly into a gas with no liquid phase. an example of this is dry ice, which go's straight from solid phase to gas phase.
