Mothballs disappear over time is it a chemical change?
No, mothballs disappearing over time is a physical change, not a chemical change. The mothballs are still the same substance, just dispersed or evaporated into the air.
Is mothballs gradually vaporize in a closet a physical or chemical change?
The gradual vaporization of mothballs in a closet is a physical change. This is because the mothballs are changing from a solid state (solid mothballs) to a gaseous state (mothball vapor) without undergoing a chemical reaction.
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 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 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.
Is sublimation of sodium chloride chemical or physical change?
Sublimation is a physical change.
Mothballs disappear over time is it a chemical change?
No, mothballs disappearing over time is a physical change, not a chemical change. The mothballs are still the same substance, just dispersed or evaporated into the air.
Is mothballs gradually vaporize in a closet a physical or chemical change?
The gradual vaporization of mothballs in a closet is a physical change. This is because the mothballs are changing from a solid state (solid mothballs) to a gaseous state (mothball vapor) without undergoing a chemical reaction.
Is the heating of iodine crystals a chemical or physical change?
It is a physical change (sublimation).
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.

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 sublimation a chemical change?
Nope, it's physical. When a material sublimes or sublimates, it changes state from a solid to a gas. Carbon dioxide does this, and so do mothballs. Nothing new is created; it's just a state change, so it's physical.
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.
Is sublimation a physical change?
Sublimation is a physical change.
Is subliming ice a chemical change?
No, subliming ice is a physical change where ice changes from a solid directly into a gas without melting into a liquid first. It is a phase transition process and does not involve any chemical reactions or changes in the chemical composition of the ice.
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.
