A liquid evaporating is a physical change. Anything changing from a solid to a liquid (or liquid to solid), or from a liquid to gas (or gas to liquid) is a physical change).

∙ 15y agoSublimining iodine is a physical change because nothing is actually happening to the original matter. Changing states (solid, liquid, gas) is not a chemical change.

Is a physical change A. an iron bar rusting B. oil floating on water C. a copper skillet tarnishing D. the sublimation of dry ice?
The answer is D; the sublimation of dry ice. A physical change alters one of the physical properties of a substance (e.g. size, shape, color, etc.), but it does not change the substance itself. A chemical change causes new substances to be formed. The new substances have different chemical properties from the original substance. Changes in the state or phase of matter, such as the sublimation of dry ice (solid carbon dioxide), are physical changes because the chemical compositions of the substances do not change. Sublimation is the change of an object from a solid-state directly to a gaseous state.
Are melting evaporation condensation and sublimation examples of physical properties or physical changes?
Yes; sublimation is the conversion of a substance from solid directly to gas. Since no chemical change occurs, simply a different state of matter, this is a physical property.
Is stapling an envelope a physical change or chemical?
A physical change
Is water condensing a chemical change?
No, it is a Physical Change. Physical Changes are concerned with energy and states of matter. A physical change does not produce a new substance. Changes in state or phase (condensation, melting, freezing, vaporization, sublimation) are physical changes. Other examples of physical changes include crushing a can, melting ice, and breaking a bottle. Chemical changes take place on the molecular level. A Chemical Change produces a new substance. Some examples of chemical changes include combustion (burning) and rusting of a metal.
Is painting a door a physical or chemical change?
Physical change of the paint, not the door.
Is sublimation of sodium chloride chemical or physical change?
Sublimation is a physical change.
Is sublime a physical change or chemical change?
Subliming (better known as sublimation) is a change in state, so it is a physical change.
Is subliming ice a chemical change?
No, sublimation is a change of state, so it is a physical process.
What is the sublimation of carbon dioxide a chemical property or chemical change?
It is a change in physical state, which is a physical change.
Is the heating of iodine crystals a chemical or physical change?
It is a physical change (sublimation).
Is disappearance of moth ball a chemical or physical change?
It is a physical change (sublimation).
Is iodine sublimating a chemical change?
No, sublimation is a physical change.
Is sublimation a physical change or physical property?
Sublimation is the physical change of a solid to a gas skipping the step of becoming a liquid. This is a physical change because you haven't changed the chemical nature of the substance. Think of when you take ice out of the freezer and you see "smoke" coming off of it. That is sublimation. The rapid change in temp caused the solid ice to skip its liquid stage and go straight to its gaseous stage
Is sublimation a physical change?
Sublimation is a physical change.
Why are sublimation and deposition are classified as physical changes?
Because sublimation and deposition doesn't change the chemical nature of the molecule.
What are the chemical reactions involves in sublimation?
Sublimation, per se, does not involve any chemical reactions. It is simply a physical change of a substance going from a solid to a gas without passing through the liquid phase.
What is dry ice physical or chemical change when left unattended?
Physical change, called sublimation. It still stays CO2
