Sublimation occurs when a substance transitions directly from a solid to a gas phase without passing through the liquid phase. This typically happens under specific temperature and pressure conditions where the vapor pressure of the solid exceeds the atmospheric pressure. Examples include dry ice (solid carbon dioxide) sublimating into carbon dioxide gas.
What else can I help you with?
Will sublimation occur for all substances if the pressure is correct?
Sublimation is the process where a substance transitions directly from a solid to a gas without passing through the liquid state. This can occur for all substances if the pressure and temperature conditions are correct for that particular substance.
How does water sublimation occur in nature and what are its implications for the environment?
Water sublimation occurs when ice or snow transitions directly into water vapor without first melting into liquid water. This process is common in cold and dry environments where the temperature and pressure conditions allow for sublimation to occur. The implications of water sublimation for the environment can be significant. In regions where sublimation is prevalent, such as polar regions and high-altitude areas, it can contribute to the loss of snow and ice cover. This can impact local ecosystems, water availability, and contribute to changes in climate patterns. Additionally, water sublimation can also affect the water cycle by bypassing the liquid phase, potentially altering precipitation patterns and water distribution in the environment.
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.
Why is sublimation rare and what are the conditions in which it typically occurs?
Sublimation is rare because it requires specific conditions of temperature and pressure for a substance to change directly from a solid to a gas without passing through the liquid phase. Typically, sublimation occurs at low pressures and temperatures where the substance's vapor pressure exceeds its triple point pressure.
Sublimation can occur because solids like liquids have a?
Sublimation can occur because solids have enough thermal energy to transition directly into a gas without passing through the liquid phase. This process happens when the vapor pressure of the solid exceeds the atmospheric pressure.
How separate the sand and camphor by sublimation process?
Sublimation of camphor occur faster by heating and sand remain.
How does sublimation occur in nature?
Snow and ice can sublime !
Sublimation occurs when?
Sublimation is when a substance turns from a solid to a gas (or the reverse). This can occur when blowing on dry ice or in volcanoes.
What planet does sublimation occur naturally on?
Sublimation occurs naturally on Earth. Snow and ice can sublimate slowly in hot sun.
How does sublimation compare with other changes of state?
Sublimation occur directly from a solid to a gas, jumping over the liquid phase.
Will sublimation occur for all substances if the pressure is correct?
Sublimation is the process where a substance transitions directly from a solid to a gas without passing through the liquid state. This can occur for all substances if the pressure and temperature conditions are correct for that particular substance.

Sublimation and deposition can occur at all temperatures at or below which?
The Critical Point
Sublimation can occur because solids like liquids have?
Vapor pressure
Explain what is meant by the sublimation of iodine at 184 C?
Sublimation of iodine at 184°C refers to the process in which solid iodine directly transitions into a gas without passing through the liquid phase. This is because the temperature at 184°C and pressure conditions allow the sublimation to occur.
When does sodium have the ability to undergo sublimation?
Probable this phenomenon occur in a sodium vapor lamp.
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.
