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.

Is a toy truck rusting an effect of physical change?
Yes, it is.
Is rusting iron a physical change in science?
no rusting iron is not a physical change it is a chemical 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 non rusting metal a physical change?
If by non rusting you mean it is in the same state it was made in then it wouldn't be part of any change. But if something is rusting it would be a chemical change because the metal is changing composition and it is not the same metal it was in the first place.
What are physical changes of an iron nail?
Anything that happens to it but can be changed back to it's original form such as melting.(not rusting)
What is an example of a physical change tarnishing rusting burning or melting?
Melting is an example of a physical change because it does not change the chemical composition of the substance undergoing the change. Tarnishing, rusting, and burning are examples of chemical change because they are caused by chemical reactions, which change the chemical composition of the substances undergoing the change.
Are rusting and tarnishing examples of corrosion?
cheeseballs!
What is rusting and burning?
They are all oxidation. Burning is much faster than the other two and releases large quantities of heat. Rusting and tarnishing are much slower. Tarnishing typically shows a change in color and very little in the way of physical change. Rusting slowly eats away the material as it combines with the oxygen.
What is the 3 chemical properties?

What would be a physical change metal rusting silver tarnishing water boiling or paper burning?
Rusting of metal and tarnishing of silver are chemical changes because new substances are formed. Boiling water is a physical change as the water changes state from liquid to gas. Burning paper is a chemical change as the paper undergoes a combustion reaction to form new substances like ash and gases.

Tarnishing typically shows a change in color and very little in the way of physical change. Rusting slowly eats away the material as it combines with the oxygen.
Why are rusting and tarnishing examples of corrosion?
Rusting and tarnishing are examples of corrosion because they involve the chemical reaction of a material with its environment, leading to degradation of the material's surface. In rusting, iron reacts with oxygen in the presence of water to form iron oxide (rust), while tarnishing involves the reaction of metals with substances in the air, such as sulfur or carbon dioxide, leading to discoloration and degradation of the material's surface.
Are tarnishing and rusting physical or chemical changes?
Tarnishing is a chemical change as it involves a reaction with the metal's surface, often due to exposure to air or moisture. Rusting is also a chemical change, specifically the oxidation of iron in the presence of oxygen and water. Both processes result in the formation of new compounds on the surface of the material.
What is an example of a physical change burning melting rusting tarnishing?
Melting! A physical change would be to change something from Solid <--> Liquid <--> Gas
