Sublimation is a physical change, not a chemical change. The best known example is when dry ice, which is solid carbon dioxide, turns into a vapor, which is just carbon dioxide gas. It skips over the liquid phase. Because you're just changing from one state of matter to another, it's a physical change just like melting ice or boiling water.

Is sublimation of sodium chloride chemical or physical change?
Sublimation is a physical change.
Is subliming ice a chemical change?
No, sublimation is a change of state, so it is a physical process.
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.
What do you call the chemical change of solid and gas?
The PHASE change of solid TO gas is called Sublimation.
Is sublimation of sodium chloride chemical or physical change?
Sublimation is a physical change.
What example of changing a substance is an example of what?
iodine'(solid) can sublime to gas. also so does camphor Sublimation is a physical change, not a chemical change. Any substance that burns demonstrates a chemical change called combustion.

Why are sublimation and deposition are classified as physical changes?
Because sublimation and deposition doesn't change the chemical nature of the molecule.
Is burning woo sublimation?
Burning is a chemical reaction between a substance and oxygen. Sublimation is a type of physical state change produced by changes in temperature and/or pressure; it is not a chemical reaction. Sublimation is not the same as combustion.
