A solid (like dry ice- solid carbon dioxide) turns directly to a gas, without being a liquid.
To be effectively purified by sublimation, a compound should have a high vapor pressure at a temperature below its melting point, be stable under sublimation conditions, and have minimal decomposition or side reactions. Additionally, the impurities should have different sublimation temperatures to allow for separation during the process.
It is slow vapourization process. This process is called evaporation.
Yes, the sublimation of iodine is a physical change, not a chemical change. Sublimation is the process by which a substance transitions from a solid directly to a gas without passing through the liquid phase. The chemical composition of iodine remains the same during sublimation.

The change from a solid directly to a gas is called sublimation. This process occurs when a solid substance bypasses the liquid phase and transforms into a gas due to increased temperature and pressure.
It is vapour formed during the process of sublimation.
During the process of Sublimation.
Neither. Sublimation is a process.
I think the answer is sublimation
During sublimation, impurities typically remain in the solid phase while the target substance transitions directly from solid to gas. As the pure substance sublimates, it leaves the impurities behind, which can be collected and discarded. This process results in a purer form of the substance, as impurities do not vaporize and are thus separated from the desired material.

Sublimation is the process when solid is turns to gas directly
To be effectively purified by sublimation, a compound should have a high vapor pressure at a temperature below its melting point, be stable under sublimation conditions, and have minimal decomposition or side reactions. Additionally, the impurities should have different sublimation temperatures to allow for separation during the process.
the change from a solid to a gas (without changing into a liquid first) is known as sublimation "Sublimation is an endothermic change (requires energy from its surroundings). As dry ice sublimes, the cold carbon dioxide vapor causes water vapor in the air to condense and form clouds."
It is slow vapourization process. This process is called evaporation.
sublimation. for example when dry ice changes directly to a gas.
Heat is absorbed during sublimation, as the process involves a solid turning directly into a gas without passing through the liquid phase. This requires energy input to break the intermolecular forces holding the solid together and to overcome the forces of attraction between the solid molecules.
