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.
Is hammered copper a physical change?
Yes, hammered copper is a physical change. When copper is hammered, its shape and size change, but its chemical composition remains the same.
Is copper one pounded into sheets is a chemical or physical change?
This is a physical change.
Is bending copper a physical of chemical change?
Yes this is a physical change because they are melting it and then it's being changed by the heat of the torch but heat is a physical change.
Is copper turing green a physical or chemical change?
It's a chemical change. Copper oxidizes to form copper oxide, which is similar to iron rusting. A color change very often indicates a chemical change.
Is turning of copper into green when exposed into environment physical or chemical change?
It is a chemical change.

its a physical change
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.
A sheet of copper can be pounded into a bowl a physical or chemical change?
Pounding a sheet of copper into a bowl is a physical change because the copper is still the same substance before and after the change. The change in shape does not alter the chemical composition of the copper.
Is a piece of copper cut in half a physical or chemical change?
Cutting a piece of copper in half is a physical change because it only alters the physical appearance of the copper without changing its chemical composition.
Is stretching copper into wire physical or chemical change?
If you meant to ask, "Is stretching copper into wire a physical or chemical change", it's a physical change.
Is copper in a Bunsen burner a physical or chemical change?
Using a Bunsen burner to heat copper is a physical change. The copper undergoes a change in its physical state from solid to liquid without changing its chemical composition.
Is stretching wire into copper a physical or chemical change?
Stretching wire into copper is a physical change because the composition of the material remains the same. The rearrangement of copper atoms in the wire does not alter the chemical identity of the substance.
The melting point of copper is 1083 C is this a chemical change or physical change?
The melting of copper is a physical change because it involves a change in the state of matter from solid to liquid without altering the chemical composition of copper itself.
Reaction of copper and heat is physical change or chemical change?
The reaction of copper with heat is a physical change because no new substances are formed. When copper is heated, it undergoes a change in state from solid to liquid without changing its chemical composition.
Is copper sulphate a physical change or chemical?
Copper sulfate dissolving in water is a physical change as no new substance is formed. However, if copper sulfate is heated to decomposition, it would be a chemical change because a new substance is formed.
