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.
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.
Is sublimation of ammonium chloride a physical change or a chemical change?
Sublimation of any pure substance such as ammonium chloride by definition is a physical change, because sublimation is defined as passage of substance from the solid to the gas phase without passing through an intermediate liquid phase.
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.
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 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.
What is the sublimation of carbon dioxide a chemical property or chemical change?
The sublimation of carbon dioxide is a physical change, not a chemical property or change. Sublimation is the process in which a substance transitions directly from a solid to a gas without going through the liquid phase, and it does not involve any change in the chemical composition of the substance.
Is the heating of iodine crystals a chemical or physical change?
It is a physical change (sublimation).
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.
Is sublimation of mothballs physical or chemical change?
Sublimation of mothballs is a physical change. Sublimation is the process of a substance transitioning from a solid directly to a gas without going through a liquid phase. It does not involve a change in the chemical makeup of the substance.
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.
Is sublimation of ammonium chloride a physical change or a chemical change?
Sublimation of any pure substance such as ammonium chloride by definition is a physical change, because sublimation is defined as passage of substance from the solid to the gas phase without passing through an intermediate liquid phase.
Is sublimation of iodine represents a chemical change?
Yes, sublimation of iodine represents a physical change. Sublimation is the process where a substance transitions from a solid directly to a gas without passing through the liquid phase, and the chemical composition of the substance remains the same.
Is disappearance of moth ball a chemical or physical change?
The disappearance of a mothball is considered a physical change. This is because there is no change in the chemical composition of the mothball when it disappears; it simply changes form from a solid into a gas through the process of sublimation.
