Chemical change
The color change of the Statue of Liberty is a physical change. It is primarily due to the natural weathering process caused by exposure to the elements, which alters the surface appearance of the copper statue over time without changing its chemical composition.
no because all you are doing is changing the shape and form
If you use a abrasive to scrape the rust off, then it is a physical change. If you utilize a chemical that combines with the rust leaving the unoxidized penny behind, then it is a chemical change.
The Statue of Liberty likely underwent a chemical change called oxidation. Before the change, the statue's copper surface was shiny and reddish-brown. After the change, the surface turned green due to the formation of a layer of copper carbonate, known as a patina, which protects the underlying copper from further corrosion.
false
Yes, acid rain damaging a marble statue is considered a physical change. The chemical composition of the marble remains the same, but the surface of the statue is physically eroded by the acidic components in the rain, leading to visible changes on the surface.
Acid rain damaging a marble statue is actually a chemical change. The acid reacts with the calcium carbonate in the marble, forming new compounds like calcium sulfate which can dissolve or wear away the statue. This chemical reaction alters the composition of the marble, leading to the visible damage.
Chemical change
No its a chemical change because the acid in the rain reacts with the copper in the statue having a reaction oxidizing it and turning it green.
i m pretty sure a colour change represents a Chemical change
The color change of the Statue of Liberty is a physical change. It is primarily due to the natural weathering process caused by exposure to the elements, which alters the surface appearance of the copper statue over time without changing its chemical composition.
Carving a statue out of marble is a physical change because the marble is simply being reshaped without undergoing a chemical reaction. The composition of the marble remains the same throughout the carving process.
It is chemical. The copper in bronze turns green when it oxidizes.

This is a physical change because wind and erosion are part of the physical category. Chemical change is where things happen involving actual chemicals . Wether the chemicals are from nature or not , Chemicals are chemicals. hope this helped ;] ~Lily
