What characteristics must a compound possess to be effectively purified by sublimation?
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.
Solid to gas with no liquid state is called?
It is slow vapourization process. This process is called evaporation.
Is iodine sublimating a chemical change?
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.

What is the change from a solid directly to a gas is called?
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.
What is the purple substance of the iodine after heating?
It is vapour formed during the process of sublimation.
During which process do ice and snow on Earth move directly from the solid state into water vapor in the atmosphere?
During the process of Sublimation.
Is sublimation an element or an atom?
Neither. Sublimation is a process.
What is the process called when ice turns into water vapor?
I think the answer is sublimation
What happens to impurities during 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.

What is the process called when a solid turns into a gas?
sublimation
Where is a sublimation?
Sublimation is the process when solid is turns to gas directly
How does dry ice turn into gas?
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."
Solid to gas with no liquid state is called?
It is slow vapourization process. This process is called evaporation.
What do you call the process of a solid changing to a gas?
sublimation. for example when dry ice changes directly to a gas.
Is heat released or absorbed during sublimination?
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.
