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.
What process could make a snowbank colder deposition or sublimation?
Sublimation because sublimation would usually occur on a warm day.
What occur only on the surface of the substance?
sublimation
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.

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.
Sublimation and deposition can occur at all temperatures at or below which?
