yes. eg: naphthanol, iodine
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, it is possible to go from a solid to a gas through a process called sublimation. Sublimation occurs when a solid turns directly into a gas without passing through the liquid state.
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'.
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.
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.
Heat creates energy, so removing heat will slow down the movement of the molecules in the system. The molecules either go from gas -> liquid -> solid, or straight from gas ->solid.
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.
The answer depends on the solid. Most solids do not turn to gas directly to gas, but melt, and then boil at a different temperature. Water does this; ice melts at 0o, and boils at 100o. Some materials go directly from solid to gas, a process called sublimation, two examples being carbon dioxide and iodine. But they do this at very different temperatures.
No, the sublime elements do not have a liquid state. Sublimation is the process in which a substance transitions directly from a solid to a gas without passing through a liquid phase. Examples of substances that sublime include dry ice (solid carbon dioxide) and camphor.
