How separate the sand and camphor by sublimation process?
Sublimation of camphor occur faster by heating and sand remain.
Explain why sublimation is regarded as a physical change but the slaking of lime is considered as a chemical change?
- Sublimation don't change the molecule; solid iodine or sublimated iodine are iodine. - Slaking of lime transform the calcium oxide in calcium hydroxide. A chemical change occur.
Why are sublimation and deposition are classified as physical changes?
Because sublimation and deposition doesn't change the chemical nature of the molecule.
How does sublimation compare with other changes of state?
Sublimation occur directly from a solid to a gas, jumping over the liquid phase.
When does sodium have the ability to undergo sublimation?
Probable this phenomenon occur in a sodium vapor lamp.
How does the process of sublimation of water occur in nature?
Sublimation of water in nature happens when ice or snow turns directly into water vapor without melting into liquid water first. This occurs when the temperature and pressure are just right for the solid ice to change into gas without becoming liquid water.
How separate the sand and camphor by sublimation process?
Sublimation of camphor occur faster by heating and sand remain.
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.
Why are sublimation and deposition are classified as physical changes?
Because sublimation and deposition doesn't change the chemical nature of the molecule.

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.
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.
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
When does sodium have the ability to undergo sublimation?
Probable this phenomenon occur in a sodium vapor lamp.
What is the name of a change that does not result in a new substance?
These changes are of physical nature as boiling, freezing, sublimation.
