Does copper turn green by a chemical or physical change?
Copper turns green due to a chemical reaction with oxygen and other elements in the environment, forming a layer of copper oxide and copper carbonate on the surface. This process is known as oxidation and is a chemical change.
Copper turns a greenish color is it chemical or physical change?
The color change of copper to green is a chemical change. This is due to the formation of a green patina on the surface of the copper, typically caused by oxidation reactions with the air and moisture.
Is copper metal turning green on exposure to air and water a physical or chemical change?
Yes it is a chemical change Because colour is changing and a new substance is forming and it's irreversible.
When A bronze statue develops a green coating (patina) over time is physical change or chemical?
It is chemical. The copper in bronze turns green when it oxidizes.
Copper turns green when exposed to the environment chemical or physical?
When copper is exposed to the elements, it reacts with oxygen and moisture to form a patina called copper oxide, which gives it a greenish color. This process is known as oxidation and is a natural occurrence with copper.

When copper turns green when exposed to the environment a physical or chemical change?
First, copper doesn't "turn green," it reacts with oxygen in the air to form copper oxide. This is a chemical change, because copper oxide is a substance that was not there before.
When copper turns green when exposed to air a physical or chemical change?
When copper turns green upon exposure to air, it undergoes a chemical change. This process occurs due to the reaction of copper with oxygen and moisture in the environment, forming copper carbonate and other compounds, commonly referred to as patina. Unlike physical changes, which do not alter the substance's chemical identity, this transformation changes the composition of the material.
Is copper metal turning green on exposure to air and water a physical or chemical change?
Yes it is a chemical change Because colour is changing and a new substance is forming and it's irreversible.
When A bronze statue develops a green coating (patina) over time is physical change or chemical?
It is chemical. The copper in bronze turns green when it oxidizes.
What is the weathering in which the chemical composition has changed?
It's called chemical weathering/chemical change. Similar to the physical change of matter, except the chemical composition changes causing it to become something completely different. For example: iron turns to rust, silver tarnishes and copper turns green.
Copper turns green when exposed to the environment chemical or physical?
When copper is exposed to the elements, it reacts with oxygen and moisture to form a patina called copper oxide, which gives it a greenish color. This process is known as oxidation and is a natural occurrence with copper.
What metal turns green when oxidized?
Copper is a metal that turns green when oxidized.
When copper oxidizesit turns?
green
Which element rust copper?
Oxygen turns copper green.
Is copper turning green in the air physical change?
The reason that copper turns green is the same reason the metal rusts, oxidization. Both metal and copper oxidize when exposed to oxygen and this is a natural process. Copper that is exposed to the outside environment is more likely to turn green and that is why copper vases and decorative pieces in gardens are often green. Copper is a metal that does not react with water (H2O), but the oxygen of the air will react slowly at room temperature to form a layer of brown-black copper oxide on copper metal which looks like green sometimes...
