State change from solid directly to gas is called sublimation, for example, dry ice - CO2(s) sublimates into gas CO2(g).
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.
This process is called sublimation. Sublimation occurs when a solid changes directly into a gas or a gas changes directly into a solid without going through the liquid phase. This happens when the substance's vapor pressure exceeds the surrounding pressure, allowing molecules to transition between solid and gas phases without an intermediate liquid phase.
Yes, a liquid can go straight to a solid through a process called freezing or solidification. This occurs when the temperature of the liquid drops below its freezing point, causing the molecules to lose energy and arrange themselves into a solid structure. Additionally, a process known as "deposition" can occur, where a gas transforms directly into a solid without passing through the liquid phase, but this does not apply to liquids.
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.
yes. eg: naphthanol, iodine
Not always. Some go straight from solid to gas eg dry ice ... called 'sublimation'.
Deposition when passing from gas to solid, sublimes when in the opposite direction.
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.
Naphthalene and camphor the process is sublimation
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.
